Answer:
The code to this question can be defined as follows:
Explanation:
C language code:
#include <stdio.h>//defining header file
int binarySearch(int x[], int l, int y, int z)//defining method binarySearch that accepts four integer parameter
{
if (y >= l)//defining if block that check r value is greater the l
{
int m= l + (y - l)/2; //defining if block that holds mid value of array
if (x[m] == z)//use if block that check value in array
return m;// return array value
if (x[m] > z) //defining if block that check array value greater then x value
return binarySearch(x, l, m-1, z);//use return keyword to call method
return binarySearch(x, m+1, y, z);// in else it use return keyword to call method
}
return -1;//return value -1
}
int main()//defining main method
{
int x[] = {2, 3, 4, 10, 40};//defining array that hold integer values
int n = sizeof(x)/ sizeof(x[0]);//use n variable to hold its size value
int z = 10;//defining x varaiable that hold integer value
int r= binarySearch(x, 0, n-1, z);//use r varaiable to hold method return value
if(r== -1) //defining if block that check its value equal to -1
printf("Number is not foud in array ");//print message
else
printf("Number is present at %d position", r);//print value
return 0;
}
C++ language code:
#include <iostream>// header file
using namespace std;
int binarySearch(int x[], int l, int y, int z)//defining method binarySearch that accepts four integer parameter
{
if (y >= l)//defining if block that check r value is greater the l
{
int m= l + (y - l)/2; //defining if block that holds mid value of array
if (x[m] == z)//use if block that check value in array
return m;// return array value
if (x[m] > z) //defining if block that check array value greater then x value
return binarySearch(x, l, m-1, z);//use return keyword to call method
return binarySearch(x, m+1, y, z);// in else it use return keyword to call method
}
return -1;//return value -1
}
int main()//defining main method
{
int x[] = {2, 3, 4, 10, 40};//defining array that hold integer values
int n = sizeof(x)/ sizeof(x[0]);//use n variable to hold its size value

int r= binarySearch(x, 0, n-1, z);//use r varaiable to hold method return value
if(r== -1) //defining if block that check its value equal to -1
cout<<"Number is not foud in array ";//print message
else
cout<<"Number is present at position "<< r;//print value
return 0;
}
Python language code:
def binarySearch (a, x, r, y):#defining a method binarySearch
if r >= x:#defining if block that checks r is greater than equal to x
m = x + (r - x)//2#defining m variable that hold mid value
if a[m] == y:#use if that check its input value equal y

elif a[m] > y:#use array that check its value greaterthan y
return binarySearch(a,x, m-1, y) #use return keyword to call method
else:#defining else block
return binarySearch(a, m+1, r, y)#use return keyword to call method
else: #defining else block
return -1#return value -1
a = [ 2, 3, 4, 10, 40 ]#defining list a that holds value
y = 10#defining integer variable
r = binarySearch(a, 0, len(a)-1, y)#defining r variable that holds method value
if r != -1:#use if that check r is not equal to -1

Answer:
Here is the corrected code:
import java.util.*;
public class DebugNine36 { //class name
public static void main(String[] args) { //start of main method
ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products
products.add("shampoo"); //add shampoo to product array list
products.add("moisturizer"); //add moisturizer product array list
products.add("conditioner"); //add conditioner product array list
Collections.sort(products); //sort the elements in products array list
display(products); //calls display method by passing products array list
final String QUIT = "quit"; //declares a variable to quit the program
String entry; //declares a variable to hold product/element or quit
Scanner input = new Scanner(System.in); //creates Scanner object
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //prompts user to enter a product or enter quit to exit
entry = input.nextLine(); //reads the entry value from user
while(!entry.equals("quit")) { //loops until user enters quit
products.add(entry); //adds entry (product) to products array list
Collections.sort(products); //sorts the elements in products array list
display(products); //calls display method by passing products arraylist
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //keeps prompting user to enter a product or enter quit to exit
entry = input.nextLine(); } } //reads the entry value from user
public static void display(ArrayList products) { // method to display the list of products
System.out.println("\nThe size of the list is " + products.size()); //displays the size of the array list named products
for(int x = 0; x < products.size(); ++x) //iterates through the arraylist products
System.out.println(products.get(x)); } } //displays each item/element in products array list
Explanation:
In the code the following statement are corrected:
1.
ArrayListproducts = new ArrayList();
This gave an error: cannot find symbol
This is corrected to :
ArrayList<String>products = new ArrayList<String>();
2.
products.add(shampoo);
products.add(moisturizer);
products.add(conditioner);
Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.
This is corrected to :
products.add("shampoo");
products.add("moisturizer");
products.add("conditioner");
3.
display();
This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .
This is corrected to :
display(products);

You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10.
Required:
List different ways that this program can be sabotaged so that during execution it computes a different sum, such as 3 to 20.
Answer:
See explanation
Explanation:
An instance of such program written in python is
isum = 0
for i in range(1,11):
isum = isum + i
print(sum)
One of the ways the program can give a wrong result is when someone alters the program source program before it's complied and executed.
Take for instance.
Changing
isum = 0 to isum = 4
will alter the result by additional 4
Another way is if an outside program or process alters the program execution.

Write a section of code to simulate the opening coin toss of a football game. The visiting team gets to choose heads or tails. If the team guesses correctly they get to choose to kick or receive. Otherwise the home team gets the same choice. Display the final result of the coin flip in form similar to below
Possibly output "home team has won the toss"
"Home team has chosen to kick first"
Or "visting team has won the toss"
"Visiting team has chosen to receive first"
Answer:
Explanation:
Which goal his team will defend: Instead of receiving the kickoff, the captain may elect to kick off and choose a goal to defend. Captains sometimes take this option if they believe that weather will be a factor in the outcome of the game. For example, in choosing which goal to defend, the player believes that his team will have the wind at its back for the second quarter and the crucial final quarter of the game.

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray

}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));
}
}
Explanation:
This line declares necessary variables
int red,blue,green,smallest;
This line prompts user for input of 3 numbers
System.out.print("Enter three numbers between 0 and 255 (inclusive): ");
The next three lines gets user inputs
red =input.nextInt();
green =input.nextInt();
blue =input.nextInt();
The following iteration checks for the smallest for red, green, blue
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
This line prints the required output
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));

Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program:
4 of Diamonds
8 of Spades
Queen of Clubs
8 of Hearts
Number of picks: 9
Answer:
Here is the JAVA program:
public class Main { //class name
public static void main(String[] args) { //start of main method
//sets all boolean type variables spades, hearts diamonds and clubs to false initially
boolean spades = false;
boolean hearts = false;
boolean diamonds = false;
boolean clubs = false;
String[] deck = new String[4]; //to store card sequence
int index = 0; //to store index position
int NoOfPicks = 0; //to store number of picks (picks count)
while (!spades || !hearts || !diamonds || !clubs) { //loop starts
String card = printCard(getRandomCard()); //calls printCard method by passing getRandomCard method as argument to it to get the card
NoOfPicks++; //adds 1 to pick count
if (card.contains("Spades") && !spades) { //if that random card is a card of Spades and spades is not false
deck[index++] = card; //add that card to the index position of deck
spades = true; //sets spades to true
} else if (card.contains("Hearts") && !hearts) { //if that random card is a card of Hearts and hearts is not false
deck[index++] = card;
hearts = true; //sets hearts to true
} else if (card.contains("Diamond") && !diamonds) { //if that random card is a card of Diamond and diamonds is not false
deck[index++] = card;
diamonds = true; //sets diamonds to true
} else if (card.contains("Clubs") && !clubs) { if that random card is a card of Clubs and clubs is not false
deck[index++] = card;
clubs = true; } } //sets clubs to true
for (int i = 0; i < deck.length; i++) { //iterates through the deck i.e. card sequence array
System.out.println(deck[i]); } //prints the card number in deck
System.out.println("Number of picks: " + NoOfPicks); } //prints number of picks
public static int getRandomCard() { //gets random card
return (int) (Math.random() * 52); } //generates random numbers of 52 range
public static String printCard(int cardNo) { //displays rank number and suit
String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs", }; //array of suits
String[] rankCards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",

This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. #include int main(void) {int arrowBaseHeight = 0;int arrowBaseWidth = 0;int arrowHeadWidth = 0;printf("Enter arrow base height:\n");scanf("%d", &arrowBaseHeight);printf("Enter arrow base width:\n");scanf("%d", &arrowBaseWidth);printf("Enter arrow head width:\n");scanf("%d", &arrowHeadWidth);printf("\n");// Draw arrow base (height = 3, width = 2)printf( "**\n");printf( "**\n");printf( "**\n");// Draw arrow head (width = 4)printf( "****\n");printf( "***\n");printf( "**\n");printf( "*\n");return 0;}a. Modify the given program to use a loop to output an arrow base of height arrow_base_height. b. Modify the given program to use a loop to output an arrow base of width arrow_base_width.c. Modify the given program to use a loop to output an arrow head of width arrow_head_width.
Answer:
Here is the C program:
#include <stdio.h> //to use input output functions
int main(void) { //start of main function
int arrowBaseHeight = 0; //stores value for arrow base height
int arrowBaseWidth = 0; //stores value for arrow base width
int arrowHeadWidth = 0 ; //stores value for arrow head width
int i, j; //to traverse through the rows and columns
printf("Enter arrow base height:\n"); //prompts user to enter arrow base height value
scanf("%d", &arrowBaseHeight); //reads input value of arrow base height
printf("Enter arrow base width:\n"); //prompts user to enter arrow base width value
scanf("%d", &arrowBaseWidth); //reads input value of arrow base width
while (arrowHeadWidth <= arrowBaseWidth) { //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth
printf("Enter arrow head width:\n"); //prompts user to enter arrow head width value
scanf("%d", &arrowHeadWidth); //reads input value of arrow head width
printf("\n"); }
for (i = 0; i < arrowBaseHeight; i++) { //iterates through rows
for (j = 0; j < arrowBaseWidth; j++) { //iterates through columns
printf("*"); } //prints asterisks
printf("\n"); } //prints a new line
for (i = arrowHeadWidth; i > 0; i--) { //loop for input length
for (j = i; j > 0; j--) { //iterates for triangle ( to make arrow head)
printf("*"); } //prints asterisks
printf("\n"); } } //prints new line
Explanation:
The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.
The loop is used to output an arrow base of height arrowBaseHeight.
The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.
The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.

The purpose of this paper is to summarize the advantages of computers/software and the use of computer technology in investigations. Summarize the disadvantages to law enforcement with respect to the advancements of computers. Real cases will be researched in order to understand how computers can be utilized in criminal activities, as well as a case that the use of a computer was beneficial to the prosecution in a criminal case. A final conclusion paragraph will address my personal subjective opinion as to whether these technologies, in an overall sense are a benefit or hindrance to law enforcement efforts.

From utilizing computers in cars so officers could run a license plate and social security number to see if there are any warrants out for the person they stopped, to more advances such as carrying cell phones, GPS tracking systems in cars, crime mapping tools, information sharing between state and local law enforcement, to even sharing information across countries. Technology has come a long way in helping officers and other agents within the criminal justice system do their job.
Just a bit more about the advantages of the things mentioned above and time to move on. The most interesting thing is Geographic Information Systems (GIS), which has become a most important tool for law enforcement agencies. GIS, other mapping software and desktop computers now are capable of mapping and data analysis that is way above and beyond what used to be possible with backroom mainframe computers (Rubley, 2011).
Another great advancement is the widespread use of everyone using mobile devices. Many officers now use two to three cell phones.

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.
The short quiz program is as follows.
Please note that comments are used to explain difficult lines.
import java.util.*;
public class shortQuiz{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
//This declares the variables that represent correct answers as boolean data type; the variables are also initialized
boolean q1 = true, q2 = false, q3 = true;
//This declares the response to each question as boolean data type
boolean q1response, q2response, q3response;
//This prints the first question
System.out.print("Java is a programming language, true or false? ");
//This gets input for the first response
q1response = input.nextBoolean();
//This prints the second question
System.out.print("Only numbers can be stored by variables in Java, true or false? ");
//This gets input for the second response
q2response = input.nextBoolean();
//This prints the third question
System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");
//This gets input for the third response
q3response = input.nextBoolean();
//This prints your first response, alongside the correct answer to the first question
System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);
//This prints your second response, alongside the correct answer to the second question
System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);
//This prints your third response, alongside the correct answer to the third question
System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);
//The program ends here
}
}

Answer:
this is AC b/c.... cos is a periodic function.. think waves... the voltage is going to vary between positive 5 and negative 5 volts... so it's a low voltage signal, but still AC, the W is for how fast it's varying and the +2 is the off set of the wave.

Scenario: You are part of an IT group managing Active Directory for a mid-size organization. A contracted research group with their own IT team operating from a remote location with a slow network connection has requested that they be able to setup a Child Domain in your organization's domain. The remote IT teams argument is based on their slow network, and their need to access and administer the local server that would need to exist in their remote location. Your team is split between allowing the Child Domain or recommending an Organizational Unit and delegating the remote IT team access. Yours is the deciding vote -- and cost is being considered a deciding factor. What option do you support as the best option in this scenario? What DC configuration for the remotely located server would be the best option?
If instead of cost, the deciding factor was the slow speed of their network, what option would you support as the best option?
Explanation:
1.
the answer to the first question is organizational unit. this is because in this scenario that we have before us, cost is a deciding factor. a unit as this can adapt to changes, it is flexible and also not very complex
2.
answer to question 2 is PDC emulator. this emulator can perform the function synchronization of time across every domain controller that is in the domain. other of its functions are, authentication and changing of passwords.
3.
the answer to the 3rd question is child domain. It is a factor in this scenario because it works well in a situation where there is an issue of slow network connection.
