Implement the function is_maxheap which takes a list of integers and returns True if the list represents a valid max-heap, and False otherwise. Assume that the list represents the contents of a complete binary tree, following the parent/child indexing conventions established in class. E.g., is_maxheap should return True for the following inputs: a) [] b) [10] c) [10, 7, 8] E.g., is_maxheap should return False for the following inputs: a) [1, 2] b) [5, 6, 3] You should not define or use any external data structures in your implementation besides the list passed in.

Answers

Answer 1

Answer:

I am writing a Python function:

def is_maxheap(list):

   #finds the length of the list  

   size=len(list)

   #loop has a variable i which starts traversing from root til end of last #internal node

   for i in range(int((size - 2) / 2) + 1):  

       if list[2 * i + 1] > list[i]:  #If left child is greater than its parent then return #false  

               return False  

       if (2 * i + 2 < size and

           list[2 * i + 2] > list[i]):    #checks if right child is greater, if yes then #returns false  

               return False

   return True

Explanation:

The function is_maxheap() traverses through all the internal nodes of the list iteratively. While traversing it checks if the  node is greater than its children or not. To check the working of this function you can write a main() function to check the working on a given list. The main() function has a list of integers. It then calls is_maxheap() method by passing that list to the function. The program displays a message: "valid max heap" if the list represents valid max-heap otherwise it returns invalid max heap.

def main():

   list = [10,7,8]  

   size = len(list)  

   if is_maxheap(list):

       print("Valid Max Heap")  

   else:  

       print("Invalid Max Heap")          

main()

The program along with its output is attached in a screenshot.

Because Java byte code is the same on all computers, compiled Java programs Group of answer choices Cannot run on Linux systems Must be re-compiled for each different machine it is run on Are highly portable Are non-existent

Answers

Answer:

Are highly portable.

Explanation:

Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.

Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.

Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.

Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.

Hence, the Java byte code is a write once, run anywhere software program.

The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).

Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.

Write a function SwapArrayEnds() that swaps the first and last elements of the function's array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10)
#include
/* Your solution goes here
*/ int main(void) {
const int SORT_ARR_SIZE = 4;
int sortArray[SORT_ARR_SIZE];
int i;
int userNum;
for (i = 0; i < SORT_ARR_SIZE; ++i) {
scanf("%d", &sortArray[i]);
}
SwapArrayEnds(sortArray, SORT_ARR_SIZE);
for (i = 0; i < SORT_ARR_SIZE; ++i) {
printf("%d ", sortArray[i]);
}

Answers

Answer:

Here is the SwapArrayEnds()

//function with two parameters; the array and array size

void SwapArrayEnds(int sortArray[],int SORT_ARR_SIZE){  

int temp;   //temporary variable to hold the first element of sortArray

if(SORT_ARR_SIZE > 1){   //if sortArray size is greater than 1

temp = sortArray[0];   // set value of temp to the first element of sortArrray

sortArray[0] = sortArray[SORT_ARR_SIZE-1];   // set the value of first element of sortArray to the last element of sortArray

sortArray[SORT_ARR_SIZE-1] = temp;  }  } // set last element  value to temp

Explanation:

Lets understand the working of the above function with the help of an example. Suppose the sortArray has the following elements: {10,20,30,40}. So the size of this array is 4.

if(SORT_ARR_SIZE > 1) has an if statement which checks if the array size is greater than 1. This condition evaluates to true as 4 > 1. So the body of if condition executes.

Next the statement temp = sortArray[0];   sets the value of temp variable to the value of first element of sortArray. As sortArray[0] means the element at 0-th index position of the sortArray. So using the above example the first element of the array is 10. So temp = 10.

Next the statement sortArray[0] = sortArray[SORT_ARR_SIZE-1];   sets the last element of the sortArray to the position of first element of the sortArray.

SORT_ARR_SIZE-1 is the position of last element of the array. As the size of sortArray is 4, so 4-1 = 3 which points to the last element. Now this element is moved to the first position of the array. This means that the value of first element of array becomes 40 as the element at 3-th index of the sortArray is 40.

Next the statement sortArray[SORT_ARR_SIZE-1] = temp moves the value in temp variable to the last position of the sortArray. As we know that the value of temp= 10. So this element 10 of the sortArray is positioned at SORT_ARR_SIZE-1 position of sortArray which is 4-1 = 3-th index of sortArray. This simply means that 10 is moved to the last position of sortArray.

So now the final sortArray becomes: 40,20,30,10 as the first and last element of the array are swapped using above function SwapArrayEnds().

The program along with the output is attached in screenshot.

Functions are collection of codes or instructions merged together to act as one.

The function, where comments are used to explain each line is as follows:

//This defines the function

void SwapArrayEnds(int sortArray[],int SORT_ARR_SIZE){  

//This increments the array element at index 0

       sortArray[0] += sortArray[SORT_ARR_SIZE-1];

//This replaces the last element with the first

       sortArray[SORT_ARR_SIZE-1]= sortArray[0]- sortArray[SORT_ARR_SIZE-1];

//This replaces the first element with the last

       sortArray[0]= sortArray[0]- sortArray[SORT_ARR_SIZE-1];

   

}

At the end of the function, the first and the last elements of the array are swapped.

//calls PrintPopcornTime function passing the value in userOunces

return 0; }

Explanation:

Function 2:  

#include <stdio.h> //header file to use input output functions

// start of the function PrintShampooInstructions body having integer variable numCycles as parameter

void PrintShampooInstructions(int numCycles){

if(numCycles < 1){

//else if part is executed when the if condition is false and else if  checks //value of numCycles is greater than 4 or not

else if(numCycles > 4){

//prints Too many in output if the above condition is true

printf("Too many.");

printf("\n"); } //prints a new line

//else part is executed when the if and else if conditions are false

else{

//prints "N: Lather and rinse." numCycles times, where N is the cycle //number, followed by Done

for(int N = 1; N <= numCycles; N++){

printf("%d",N);

printf(": Lather and rinse. \n");}

printf("Done.");

printf("\n");} }

int main() //start of the main() function body

{    int userCycles; //declares integer variable userCycles

   scanf("%d", &userCycles); //reads the input value into userCycles

   PrintShampooInstructions(userCycles);

//calls PrintShampooInstructions function passing the value in userCycles

   return 0;}

I will explain the for loop used in PrintShampooInstructions() function. The loop has a variableN  which is initialized to 1. The loop checks if the value of N is less than or equal to the value of numCycles. Lets say the value of numCycles = 2. So the condition evaluates to true as N<numCycles  which means 1<2. So the program control enters the body of loop. The loop body has following statements. printf("%d",N); prints the value of N followed by

printf(": Lather and rinse. \n"); which is followed by printf("Done.");

So at first iteration:

printf("%d",N); prints 1 as the value of N is 1

printf(": Lather and rinse. \n");  prints : Lather and rinse and prints a new line \n.

As a whole this line is printed on the screen:

1: Lather and rinse.

Then the value of N is incremented by 1. So N becomes 2 i.e. N = 2.

Now at second iteration:

The loop checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to true as N<numCycles  which means 2=2. So the program control enters the body of loop.

printf("Done."); prints Done after the above two lines.

printf("%d",N); prints 2 as the value of N is 2

printf(": Lather and rinse. \n");  prints : Lather and rinse and prints a new line \n.

As a whole this line is printed on the screen:

2: Lather and rinse.

Then the value of N is incremented by 1. So N becomes 2 i.e. N = 3.

The loop again checks if the value of N is less than or equal to the value of numCycles. We know that the value of numCycles = 2. So the condition evaluates to false as N<numCycles  which means 3>2. So the loop breaks.

Now the next statement is:

printf("Done."); which prints Done on the screen.

So as a whole the following output is displayed on the screen:

1: Lather and rinse.

2: Lather and rinse.

Done.

(Displaying a Sentence with Its Words Reversed) Write an application that inputs a line of text, tokenizes the line with String method split and outputs the tokens in reverse order. Use space characters as delimiters.

Answers

Answer:

I am writing a JAVA and Python program. Let me know if you want the program in some other programming language.

import java.util.Scanner; // class for taking input from user

public class Reverse{ //class to reverse a sentence

public static void main(String[] args) { //start of main() function body

Scanner input = new Scanner(System.in); //create a Scanner class object

   System.out.print("Enter a sentence: "); //prompts user to enter a sentence

   String sentence = input.nextLine(); // scans and reads input sentence

   String[] tokens = sentence.split(" "); // split the sentence into tokens using split() method and a space as delimiter

   for (int i = tokens.length - 1; i >= 0; i--) { //loop that iterates through the tokens of the sentence in reverse order

       System.out.println(tokens[i]); } } } // print the sentence tokens in reverse order

Explanation:

In JAVA program the user is asked to input a sentence. The sentence is then broken into tokens using split() method. split method returns an array of strings after splitting or breaking the sentence based on the delimiter. Here the delimiter used is space characters. So split() method splits the sentence into tokens based on the space as delimiter to separate the words in the sentence. Next the for loop is used to iterate through the tokens as following:

Suppose the input sentence is "How are you"

After split() method it becomes:

How

are

you

Next the loop has a variable i which initialized to the tokens.length-1. This loop will continue to execute till the value of i remains greater than or equals to 0.

for (int i = tokens.length - 1; i >= 0; i--)

The length of first token i.e you is 3 so the loop executes and prints the word you.

Then at next iteration the value of i is decremented by 1 and now it points at the token are and prints the word are

Next iteration the value of i is again decremented by i and it prints the word How.

This can be achieved in Python as:

def reverse(sentence):

   rev_tokens = ' '.join(reversed(sentence.split(' ')))

   return rev_tokens

   

line = input("enter a sentence: ")

print((reverse(line)))

The method reverse takes a sentence as parameter. Then rev_tokens = ' '.join(reversed(sentence.split(' ')))  statement first splits the sentence into array of words/tokens using space as a delimiter. Next reversed() method returns the reversed sentence.  Next the join() method join the reversed words of the sentence using a space separator ' '.join(). If you want to represent the reversed tokens each in a separate line then change the above statement as follows:

rev_tokens = '\n'.join(reversed(sentence.split(' ')))  

Here the join method joins the reversed words separating them with a new line.

Simply input a line of text and call this reverse() method by passing the input line to it.

The score of a student in two subjects are inserted in the B2 and C2 cells and the passing score for each subject is 60. Which of these functions will you insert in the D2 cell so that it returns TRUE if at least one score is greater than or equal to 60, or else it returns FALSE

Answers

Answer:

=OR(B2>=60, C2>=60)

Explanation:

If you want to check if at least one of the scores is equal to or greater than 60, you should use the OR function. The OR function tests multiple conditions and returns TRUE if at least one is met. Therefore, the function in cell D2 would be:

= OR(B2>=60, C2>=60)

In other to obtain the boolean value True if one of two or more conditions are met, the OR operator is used. Hence, the appropriate function is =OR(B2>=60, C2>=60)

The OR opertor gives a True value if one of the two conditions is met., if the student scores 60 or above in one of the two subjects, the output will be True.

Similarly, if the student score above 60 in both, the output will be true.

Hence, the appropriate function is =OR(B2>=60, C2>=60).

a. A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2, 048 sectors and there are 131, 072 (2^17) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk?

b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)

Answers

Answer:

Explanation:

Given that:

number of surfaces on a hard disk = 4

number of sectors = 2048 sectors

number of tracks per surface = 131, 072 (2^17)

a block holds 512 bytes.

Since, 'The disk is not "zoned.".....

then, Number of bytes / sector = 512

a) What is the total capacity of this disk?

The total capacity of the disk is:[tex]= 4 \ surfaces \times 131072 \dfrac{tracks}{surfaces} \times 2048 \dfrac{sector}{tracks} \times 512 \dfrac{bytes}{sector}[/tex]

[tex]= 5.49755814\times 10^{11} \ bytes[/tex]

= 549755814 KB ( kilobytes)

= 549755.814 MB (megabytes)

=549.755814  GB (gigabytes)

b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (i.e what is the capacity of one cylinder?)

The capacity of one cylinder can be estimated by determining the capacity of one surface and the capacity of one track.

The capacity of one surface = [tex]131072\dfrac{tracks}{surface} \times 2048 \dfrac{sector}{tracks} \times 512\dfrac{bytes}{sector}[/tex]

The capacity of one surface = [tex]1.37438953 \times 10^{11[/tex] byte = 137.44 GB

Capacity of one track = 2048 sectors/track × 512 bytes/sector

Capacity of one track = 1048576 Bytes/track

Capacity of one track =1048 KB/track

Capacity of one track ≅ 1 MB/track

Since the hard disk contains four surfaces

capacity of one cylinder = 1 MB/track × 4 track/cylinder

capacity of one cylinder  = 4 MB

Write a method named isPalindrome that accepts a string parameter and returns true if that string is a palindrome, or false if it is not a palindrome. For this problem, a palindrome is defined as a string that contains exactly the same sequence of characters forwards as backwards, case-insensitively. For example, "madam" or "racecar" are palindromes, so the call of isPalindrome("racecar") would return true. Spaces, punctuation, and any other characters should be treated the same as letters; so a multi-word string such as "dog god" could be a palindrome, as could a gibberish string such as "123 $$ 321". The empty string and all one-character strings are palindromes by our definition. Your code should ignore case, so a string like "Madam" or "RACEcar" would also count as palindromes.

Answers

Answer:

The programming language is not stated;

However, I'll answer this question using Java Programming Language;

The method is as follows;

   public static void isPalindrome(String userinput)

    {

       String reverse = "";

       int lent = userinput.length();

int j = lent - 1;

while(j >= 0)

       {

           reverse = reverse + userinput.charAt(j);

           j--;

       }

       if(reverse.equalsIgnoreCase(userinput))

       {

           System.out.println("True");

       }

       else

       {

           System.out.println("False");

       }    

    }

Explanation:

This line defines the method isPalindrome with a string parameter userinput

public static void isPalindrome(String userinput) {

This line initializes a string variable

       String reverse = "";

This line gets the length of the userinput

       int len = userinput.length();

The following while-loop gets the reverse of userinput and saved the reversed string in reverse

int j = lent - 1;

while(j >= 0)

       {

           reverse = reverse + userinput.charAt(j);

           j--;

       }

The following if statement checks if userinput and reverse are equal (cases are ignored)

       if(reverse.equalsIgnoreCase(userinput))

       {

           System.out.println("True"); This line is executed if the if condition is true

       }

       else

       {

           System.out.println("False"); This line is executed if otherwise

       }  

    } The method ends here

A network technician is designing a network for a small company. The network technician needs to implement an email server and web server that will be accessed by both internal employees and external customers. Which of the following would best secure the internal network and allow access to the needed servers?
A. Implementing a site-to-site VPN for server access.B. Implementing a DMZ segment for the server.C. Implementing NAT addressing for the servers.D. Implementing a sandbox to contain the servers.

Answers

Answer:

Option A (Implementing a site-to-site VPN for server access) seems to be the correct choice.

Explanation:

A site-to-site configuration is something that a single Open VPN network links several more separate networks linked. Technologies through one network will access machines in all the other computer systems in that connection model, including conversely. Implementing this would be extremely straightforward, for as much further even though Access Server was indeed implicated.The much more challenging aspect happens when interacting regarding firewalls including privacy filtering methods, as well as modifying the forwarding table in internet gateways, as several of them from different manufacturers but instead prototypes which they may not be able to log many of these.This rather gateway device uses an Open VPN with a Linux VPN client, to create a connection between various channels. If someone's server hardware is also measured accurately then perhaps a site-to-site configuration could be accomplished which works straightforwardly throughout all systems in both cable systems.

Other choices are not related to the given instance. So that Option A would be the right one.

Letm1, m2,···mnbe distinct numbers on the number line, in the increasing order. Your goalis to color all of them blue. You have magical blue pens with the following property: Whenyou place the pen at co-ordinate x, all the points in the range [x - 5, x + 5] turn blue. Apen can be used only once. Give an algorithm to color all the points using as few pens aspossible. Prove the correctness of the algorithm and derive the runtime.

Answers

Answer:

Following are the algorithm to this question:

y = 0 //  initialize variable y that assigns the value  0

p = 1 // initialize value 1 in the variable p which also known as starting position

init num = 1//define variable num that assign value 1

for j = 1 to n: //defining loop

y = m[j] - m[p]

if (y > 10) //defining if block

num++;  //increment num variable

p=i; //holding loop value in p variable

y= 0//assign value 0 in y variable

Explanation:

Following are the runtime analysis of the above-given algorithm:

The above-provided algorithm is greedy, but if it doesn't exceed the scope, it operates by greedily choosing its next object. Therefore the algorithm selects the fewest number of pens.

Running time:

This algorithm merely iterates once over all the points. The run-time is therefore O(n).

In the Programming Process which of the following is not involved in defining what the program is to do:_____________ Group of answer choices

a. Compile code
b. Purpose
c. Output
d. Input
e. Process

Answers

Answer:

a. Compile code

Explanation:

In programming process, the following are important in defining what a program is to do;

i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program.  The purpose of a program should be defined in the program.

ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.

iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.

iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.

Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

Answers

Answer:

Following are the answer to this question:

Explanation:

A)

The memory size is 1 Giga Bytes which is equal to [tex]2^{30}[/tex]

[tex]\texttt{Number of address bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ Number of addresses}\\\\ \ \ \ \ 30 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2^{30}= 1073741824[/tex]

B) [tex]\texttt{I \ \ \ Opcode \ \ \ Register address \ \ \ Immediate operand \ \ \ Memory address}\\\\\\\textt{1 \ bit \ \ \ \ \ \ 128 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 24 \ bits \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 30 \ bits}\\\\\\[/tex]            [tex]= 2^7 \\\\ = 7 \ bits[/tex]

calculating the register Bits:

[tex]= 64-(1+7+24+30)\\\\=64 -62\ \ bits\\\\= 2\ \ bits\\[/tex]

C)

Immediate value size while merging the additional benefit with the address field:

[tex]= 2^{24} + 2^{30}\\\\= 2^{54}\\\\[/tex][tex]\texttt{Range before combining(-,+) 24 bits \ \ \ \ \ \ Range after combining( -,+)54bits}\\\\[/tex]                         [tex]\textt{-2^{12} from + (2^{12}-1) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -2^{27} from + (2^{27}- 1)}[/tex]

[tex]= \frac{24}{2} = 12\\\\= \frac{54}{2} = 27[/tex]

The range is accomplished by dividing the bits by 2 into the two sides of the o and the number is one short to 0.

Modify short_names by deleting the first element and changing the last element to Joe. Sample output with input: 'Gertrude Sam Ann Joseph'

Answers

Answer:  

I am writing a Python program:

For taking input from user:

user_input = input() # takes input from user

short_names = user_input.split() #splits user_input into list of strings

short_names.pop(0) # removes the first element of the list i.e. Gertrude

short_names[-1] = "Joe" #sets the last element to Joe

print(short_names)    #prints modified list of Sam Ann Joe

If you do not want to take input from user:  

short_names=['Gertrude', 'Sam', 'Ann', 'Joseph']  #list of 4 elements

short_names=short_names[1:]  # removes the first element Gertrude

short_names.pop()  # removes last element i.e. Joseph from list

short_names.append('Joe')  #adds Joe to the end of the list

print(short_names) #prints modified list Sam Ann Joe

If you do not want to use pop() and append() methods:

short_names = ['Gertrude', 'Sam', 'Ann', 'Joseph']  #creates list of 4 values

short_names = short_names[1:]  # removes first value i.e. Gertrude from list

short_names[-1] = "Joe"  #set the last element to Joe

print(short_names) #prints modified list Sam Ann Joe

Explanation:

The first program takes the names from the user, splits them into list of strings, then pop(0) has given index value 0 which means 1st value in the list. So it removes and returns first value from the list. Next statement sets the last value of list to Joe.

The second program has a hard coded list ['Gertrude', 'Sam', 'Ann', 'Joseph']  

short_names = short_names[1:] removes the first value of the short_names list i.e. Gertrude. Next pop() removes and returns last value in the list i.e. Joseph from list. Last statement append('Joe') adds Joe to the end of the list.

The third program has a list of 4 elements. short_names = short_names[1:]   removes first value i.e. Gertrude from list and short_names[-1] = "Joe"  sets the last element to Joe.

The function was implemented using the JavaScript language, the shift, pop and push function was used to get the desired output

Array and String Operations

The function bellow is written in JavaScript

function shortName (short_names){

short_names.shift() // The first element "Gertrude" was removed

short_names.pop() //The last element "Joseph" was removes

short_names.push("joe") //"Joe" is added to the new list

return short_names //The new list is returned as output
