A lot of people call AES as an algorithm because it adopts Rijndael as a Standard. However, AES is more specific so that all implementations of AES conform to the 'standard' and are therefore inter-operable - meaning they can talk to each other. One of the things that AES takes care is how diffusion is implemented. It is implemented as a combination of shiftrows and mixcolumns. The shiftrows is simply:________

a. permutation of data at byte level.
b. using many keys.
c. same as mixcolumns.
d. using substitution box.

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).

Answer:

Explanation:

In data communications, a protocol is connectionless if it describes communication between two devices in a network without first establishing or verifying establishment of some link (connection) between the two devices. In a connectionless protocol, data are exchanged between processes or devices without a prior check of whether the processes are ready to transmit data or not. In this type of protocol, there's no verification put in place to remember if these processes were or are in communication. Connectionless protocols are also called stateless protocols. Because connectionless protocol cannot be relied upon due to its lack of delivery-assurance policy, it is sometimes referred to as unreliable protocol. In other words, delivery of data packets is not guaranteed. An example of a connectionless protocol is the UDP (User Datagram Protocol).

However, if the protocol defines some checks to ascertain that there is first a connection between two communicating processes before beginning transmission, then, the protocol is connection-oriented. An example of this is the TCP (Transmission Control Protocol). Connection-oriented protocols are reliable since they ensure connection be made between processes before transmitting data packets.

A typical application of a connectionless/unreliable protocol is in the streaming of real time videos or voice communication where packets of data could be dropped and not resent.

An example of the connection-oriented/reliable protocol is analogous to making a telephone call where data packets (voice messages) are not sent until the receiver on the other end makes a connection.

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

Explanation:

Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.

Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.

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.

Answer:

true

Explanation:

else if used so I think it's true

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

//calls PrintPopcornTime function passing the value in userOunces

return 0; }

Explanation:

#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){

//if conditions checks value of numCycles is less than 1 or not

printf("Too few."); //prints Too few in output if the above condition is true

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

//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.

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.

Answer:

C. The main method proceeds to the next statement following the t3.join(); statement

Explanation:

join() method allows the thread to wait for another thread and completes its execution. If the thread object is executing, then t3.join() will make that t is terminated before the program executes the instruction. Thread provides the method which allows one thread to another complete its execution. If t is a thread object then t.join() will make that t is terminated before the next instruction. There are three overloaded functions.

join()

join(long mills)

join(long millis, int Nanos)

If multiple threads call the join() methods, then overloading allows the programmer to specify the period. Join is dependent on the OS and will wait .

141.95|212.95|312.95|10.95|

Reformatting the code snippet and giving it line numbers;

1.       var totals = [141.95, 212.95, 411, 10.95];

2.      totals[2] = 312.95;

3.      var totalsString = "";

4.      for (var i = 0; i < totals.length; i++) {

5.          totalsString += totals[i] + "|";

6.      }

Line 1 creates an array called totals with four elements.

     First element = totals[0] =141.95

     Second element = totals[1] = 212.95

     Third element = totals[2] = 411

     Fourth element = totals[3] = 10.95

Line 2 replaces the value of the third element totals[2] = 411 with 312.95.

     Therefore the array totals = [141.95, 212.95, 312.95, 10.95]

Line 3 creates an empty string called totalsString

Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length

       totals.length = 4 (which is the number of items in the array totals)

       This means that the loop cycles from i=0 to i<4

       During cycle 1 when i = 0, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[0] + "|"   //substitute the values

            totalsString = "" + 141.95 + "|"

            totalsString = 141.95|

       During cycle 2 when i = 1, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[1] + "|"   //substitute the values

            totalsString = "141.95|" + 212.95 + "|"

            totalsString = 141.95|212.95|

       During cycle 3 when i = 2, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[2] + "|"   //substitute the values

            totalsString = "141.95|212.95|" + 312.95 + "|"

            totalsString = 141.95|212.95|312.95|

       During cycle 4 when i = 3, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[3] + "|"   //substitute the values

            totalsString = "141.95|212.95|312.95|" + 10.95 + "|"

            totalsString = 141.95|212.95|312.95|10.95|

At the end of the execution, totalsString = 141.95|212.95|312.95|10.95|

The answer is A, testing the circuit at the power source.

Answer:

True

Explanation:

It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.

Hope this helps.

The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:

This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.

With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

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

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

}

Answer:

Here is the Python code.

import csv  

inputfile = input("Enter name of the file: ")

count = {}

with open(inputfile, 'r') as csvfile:

 csvfile = csv.reader(csvfile)

 for line in csvfile:

   for words in line:

     if words not in count.keys():

       count[words] = 1

     else:

         count[words] + 1

   print(count)

Explanation:

I will explain the code line by line.

import csv   here the css is imported in order to read the file using csv.reader() method

inputfile = input("Enter name of the file: ")  This statement takes the name of the input file from the user

count = {}  this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.

with open(inputfile, 'r') as csvfile:  This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type

 csvfile = csv.reader(csvfile)  This statement uses csv.reader() method to read the csv file contents.

for line in csvfile:  This outer for loop iterates through each line of the file

for words in line:  This inner loop iterates through each word in the line

if words not in count.keys():  This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary

count[words] = 1  if the word is not present already then assign 1 to the count dictionary

co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:

hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy

Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:

{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}

But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:  

count[words] = count[words] + 1

So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:

{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}  

You can see that cat, boy, dog and hey appear twice in the file.                    

print(count) This statement prints the dictionary contents with words and their frequencies.

The program with its output is attached.

The program is an illustration of file manipulations.

File manipulations involve reading from and writing into files.

The program in Python, where comments are used to explain each line is as follows:

#This imports csv module

import csv  

#This initializes a dictionary

kounter = {}

#This gets input for the file name

fname = input("Filename: ")

#This opens and iterates through the file

with open(fname, 'r') as cfile:

   #This reads the csv file

   cfile = csv.reader(cfile)

   #This iterates through each line

   for line in cfile:

       #This iterates through each word on each line

       for words in line:

           #This counts the occurrence of each word

           if words not in kounter.keys():

               kounter[words] = 1

           else:

               kounter[words] + 1

#This prints the occurrence of each word

print(kounter)

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.

Answer:

The program is written in python and it doesn't make use of any comment;

(See explanation section for line by line explanation)

def getN(num):

     fact = 1

     for i in range(1, 1 + num):

           fact = fact * i

     print("Factorial: ",fact)

num = int(input("Number: "))

if num < 0:

     print("Invalid")

else:

     getN(num)

Explanation:

The function getNum is defined here

def getN(num):

Initialize the result of the factorial to 1

     fact = 1

Get an iteration from 1 to the user input number

     for i in range(1, 1 + num):

Multiply each number that makes the iteration

           fact = fact * i

Print result

     print("Factorial: ",fact)

Ths line prompts user to input number

num = int(input("Number: "))

This line checks if user input is less than 0; If yes, the program prints "Invalid"

if num < 0:

     print("Invalid")

If otherwise, the program calls the getN function

else:

     getN(num)
