Given an array

1. myArray of numbers, write a JS program to perform the following steps and log the result. Multiply each value with 9.
2. Subtract 20 from each value.
3. Multiply each value with 7.
4. Log the values of the resulting array separated by a space.

Sample Input

[ 12, 2, 2, 4, 1 ]

Sample Output

616 -14 -14 112 -77

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

/* Please do not modify anything above this line */

function main() {

 const myArray = JSON.parse(readLine());

 /* Write your code here */

}

Given an array nestedArray of arrays, write a JS program to multiply the values in the sub-array if at least one of its values is even else return zero.

Sample Input 1

[ [ 12, 1, 2, 4, 1 ], [ 18, 20, 30, 45 ], [ 49, 11, 13, 21 ] ]

[ 96, 486000, 0 ]

Sample Input 2

[ [ 0, 1 ], [ 1, 3, 4 ] ]

Sample Output 2

[ 0, 12 ]

"use strict";

process.stdin.resume();

process.stdin.setEncoding("utf-8");

let inputString = "";

let currentLine = 0;

process.stdin.on("data", (inputStdin) => {

 inputString += inputStdin;

});

process.stdin.on("end", (_) => {

 inputString = inputString.trim().split("\n").map((str) => str.trim());

 main();

});

function readLine() {

 return inputString[currentLine++];

}

/* Please do not modify anything above this line */

function main() {

 const nestedArray = JSON.parse(readLine());

 /* Write your code here */

Write a javascript program that asks the user to enter his or her first name and then last name, and then constructs, stores, and displays a third string consisting of the user’s last name followed by a comma, a space, and first name. Use string objects and methods from the string header file. A sample run could look like this: Enter your first name: Paul Enter your last name: Smith Here’s the information in a single string: Smith, Paul 

Write a javascript program that asks the user to enter up to 10 golf scores, which are to be stored in an array. You should provide a means for the user to terminate input prior to entering 10 scores. The program should display all the scores on one line and report the average score. Handle input, display, and the average calculation with three separate array processing functions. 

(Tic-Tac-Toe) Create a class Tic-Tac-Toe that will enable you to write a program to play Tic-Tac-Toe. The 

class contains a private 3-by-3 two-dimensional array. Use an enumeration to represent the value in 

each cell of the array. The enumeration’s constants should be named X, O and EMPTY (for a position 

that does not contain an X or an O). The constructor should initialize the board elements to EMPTY. 

Allow two human players. Wherever the first player moves, place an X in the specified square, and place 

an O wherever the second player moves. Each move must be to an empty square. After each move, 

determine whether the game has been won and whether it’s a draw. Also, allow the player to specify 

whether he or she wants to go first or second.
