Can you figure out what it is? (b) Rewrite the script using vectors and array operations. M.sc. Zena Ahmed 2016 36 MATLAB Section4 Q6:Work through the following script by hand. Draw up a table of the values of i, j and m to show how their values change while the script executes. Check your answers by running the script. v = [31 5]; i = 1; for j = v i=i+ 1; if i == 3 i=i+ 2; m = i+j; end end

Java question Write a program that plays the Rock-Paper-Scissors game againstthe computer. When played between two people, each personpicks one of three options (usually shown by a hand gesture) atthe same time, and a winner is determined. In the game, Rockbeats Scissors, Scissors beats Paper, and Paper beats Rock. The program should randomly choose one of the three options (with-out revealing it), then prompt for the user's selection. At that point, the program reveals both choices and prints a statementindicating if the user won, the computer won, or if it was a tie.Continue playing until the user chooses to stop, then print thenumber of user wins, losses, and ties.
Assign Barbecue's data member numberOfCalories with a value read from input. Then, assign Ham and Cheese's data member numberOfCalories with another value read from input. Input will contain two integer numbers. Only the *your code goes here can be affected, the rest of the program cannot be changed. Program below: ----------------------------#include <iostream>#include <vector>#include <string>using namespace std; struct PizzaInfo {string pizzaName;int numberOfCalories;}; int main() {vector<PizzaInfo> availablePizzas(2); availablePizzas.at(0).pizzaName = "Barbecue";availablePizzas.at(1).pizzaName = "Ham and Cheese"; /* Your code goes here */ cout << "A " << availablePizzas.at(0).pizzaName << " slice contains " << availablePizzas.at(0).numberOfCalories << " calories." << endl;cout << "A " << availablePizzas.at(1).pizzaName << " slice contains " << availablePizzas.at(1).numberOfCalories << "…

Q1: Can you read this question carefully rebug and type the answers Debug Problem 1: As an intern for The Weather Channel, you have been instructed to debug a java program that converts Celsius to Fahrenheit. If the formula runs correctly, then 12 degrees in Celsius should give 54 degrees in Fahrenheit . Here is the formula given and it might not be correctly stated in terms of () needed and the order of operations. Google a reputable site if needed.: °F = °C x 9/5 + 32 Remember that there may be more than one problem to fix. It could be that variables have an incorrect data type. It could be that the formula is not coded correctly. Also, some import statements could be missing. Copy and paste the code below in JGrasp and debug the code. Here is the code to debug: // Convert Celsius to Fahrenheit class CelsiusToFahr { public static void main (String args[]) { Scanner keyboard = new Scanner(System.in); int celsius = 0; int fahr = 0; System.out.println("Input the degrees in…
