A "Pythagorean Triple" is a set of integers which will make the sides of a right triangle when used in the calculation of Pythagoras’ Theorem. For example, "3, 4, 5" is a Pythagorean Triple. Write a short "C" function that takes three decimal integers and determines if they are a "Pythagorean Triple". The function should return a boolean which is true if the three numbers fit the pattern, and false otherwise. DO NOT write a "main()" method in this code! [15 pts.]
Answer:
The function in C is as follows:
bool checkPythagoras(int a, int b, int c ){
bool chk = false;
if(a*a == b*b + c*c || b*b == a*a + c*c || c*c == b*b + a*a){
chk = true;
}
return chk;
}
Explanation:
This defines the function. It receives three integer parameters a, b and c
bool checkPythagoras(int a, int b, int c ){
This initializes the return value to false
bool chk = false;
This checks if the three integers are Pythagorean Triple
if(a*a == b*b + c*c || b*b == a*a + c*c || c*c == b*b + a*a){
If yes, the return value is updated to true
chk = true;
}
This returns true or false
return chk;
}
Write a function template that accepts an argument and returns its absolute value. The absolute value of a number is its value with no sign. For example, the absolute value of -5 is 5, and the absolute value of 2 is 2. Test the template in a simple driver program being sure to send the template short, int, double, float, and long data values.
Answer:
The function in Java is as follows:
public static double func(double num){
num = Math.abs(num);
return num;
}
Explanation:
This defines the function
public static double func(double num){
This determines the absolute function of num
num = Math.abs(num);
This returns the calculated absolute value
return num;
}
Write a recursive method named factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 * 2 * 3 * 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit in the range of type int. Do not use loops or auxiliary data structures; solve the problem recursively.
Answer:
The function in Python is as follows:
def factorial(n):
if n == 1 or n == 0:
return n
else:
return n*factorial(n-1)
Explanation:
This defines the function
def factorial(n):
This represents the base case (0 or 1)
if n == 1 or n == 0:
It returns 0 or 1, depending on the value of n
return n
If n is positive, then this passes n - 1 to the factorial function. The process is repeated until n = 1
else:
return n*factorial(n-1)
Write a Java program named Problem 3 that prompts the user to enter two integers, a start value and end value ( you may assume that the start value is less than the end value). As output, the program is to display the odd values from the start value to the end value. For example, if the user enters 2 and 14, the output would be 3, 5, 7, 9, 11, 13 and if the user enters 14 and 3, the output would be 3, 5, 7, 9, 11, 13.
Answer:
hope this helps
Explanation:
import java.util.Scanner;
public class Problem3 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter start value: ");
int start = in.nextInt();
System.out.print("Enter end value: ");
int end = in.nextInt();
if (start > end) {
int temp = start;
start = end;
end = temp;
}
for (int i = start; i <= end; i++) {
if (i % 2 == 1) {
System.out.print(i);
if (i == end || i + 1 == end) {
System.out.println();
} else {
System.out.print(", ");
}
}
}
}
}
The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.

Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride, the company's app estimates the minutes until the nearest driver can arrive. Write a method that, given the x and y coordinates of a customer and the three nearest drivers, returns the estimated pickup time. Assume drivers can only drive in the x or y directions (not diagonal), and each mile takes 3.5 minutes to drive. All values are doubles; the coordinates of the user and of the drivers are stored as arrays of length 2. 289222.1780078.qx3zqy7
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main (String[]args){
Scanner input = new Scanner(System.in);
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
System.out.print("Enter user coordinates: ");
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
System.out.print("Enter driver 1 coordinates: ");
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
System.out.print("Enter driver 2 coordinates: ");
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
System.out.print("Enter driver 3 coordinates: ");
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");
}
}
Explanation:
The following array declarations are for the customer and the three drivers
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
This prompts the user for the customer's coordinates
System.out.print("Enter user coordinates: ");
This gets the customer's coordinate
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
This prompts the user for the driver 1 coordinates
System.out.print("Enter driver 1 coordinates: ");
This gets the driver 1's coordinate
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
This prompts the user for the driver 2 coordinates
System.out.print("Enter driver 2 coordinates: ");
This gets the driver 2's coordinate
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
This prompts the user for the driver 3 coordinates
System.out.print("Enter driver 3 coordinates: ");
This gets the driver 3's coordinate
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
This calculates the distance between driver 1 and the customer
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
This calculates the distance between driver 2 and the customer
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
This calculates the distance between driver 3 and the customer
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
The following print statements print the estimated pickup time of each driver
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

Suppose that a minus sign in the input indicates pop the stack and write the return value to standard output, and any other string indicates push the string onto the stack. Further suppose that following input is processed:
this parrot - wouldn't voom - if i put -- four thousand --- volts - through it -
What are the contents (top to bottom) left on the stack?
a. through wouldn't this.
b. this wouldn't through.
c. it through wouldn't.
d. it through volta.
e. volts through it.
Answer:
e. volts through it
Explanation:
volts through it
The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.
What is standard output?When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).
A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.
The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.

Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used-times.
b was used - times.
c was used - times .... ...and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array|
| Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]:
Answer:
#include <stdio.h>
#include <ctype.h>
void printHistogram(int counters[]) {
int largest = 0;
int row,i;
for (i = 0; i < 26; i++) {
if (counters[i] > largest) {
largest = counters[i];
}
}
for (row = largest; row > 0; row--) {
for (i = 0; i < 26; i++) {
if (counters[i] >= row) {
putchar(254);
}
else {
putchar(32);
}
putchar(32);
}
putchar('\n');
}
for (i = 0; i < 26; i++) {
putchar('a' + i);
putchar(32);
}
}
int main() {
int counters[26] = { 0 };
int i;
char c;
FILE* f;
fopen_s(&f, "story.txt", "r");
while (!feof(f)) {
c = tolower(fgetc(f));
if (c >= 'a' && c <= 'z') {
counters[c-'a']++;
}
}
for (i = 0; i < 26; i++) {
printf("%c was used %d times.\n", 'a'+i, counters[i]);
}
printf("\nHere is a histogram:\n");
printHistogram(counters);
}

In a spreadsheet, the $ symbol is the symbol of the dollar. The dollar is the currency of the United States.
What is currency?Currency is a form of payment for goods and services. In a nutshell, it is money in the form of paper and coins that is usually issued by a government and is generally accepted as a form of payment at face value.
Currency exchange rates differ between businesses because each one distorts the interbank rate to maximize profits. We encounter numerous competitors who post interbank rates internet as bait to attract new customers, but once the customers are onboard, they drastically change the rate, typically not in the customers' favor.
Therefore, the $ symbol represents the dollar in a spreadsheet. The US dollar is the country's currency.
