SERIES OF OPERATIONS

myArray of numbers, write a JS program to perform the following steps and log the result.

Multiply each value with 9.

Subtract 20 from each value.

Multiply each value with 7.

Log the values of the resulting array separated by a space.

Input

The input will be a single line containing an array myArray

Output

The output should be a single line with values separated by a space

Constraints

Each value in the array must be a number

Sample Input

[ 12, 2, 2, 4, 1 ]

Sample Output

616 -14 -14 112 -77

"use strict";

process.stdin.resume();

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++];

}

function main() {

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

  /* Write your code here */

}

Lucky Pairs

Write Java script program to count the number of lucky pairs.

Two numbers are said to be lucky pairs . if first number is divided by second number and second number is divided by first number. given an integer N . find all possible combinations of lucky pairs.

input:

2

output:

2

Explanation:

input is 2

possible combinations are [1,2],[2,1].here in [1,2]1 is divisible by 2, and in [2,1] 2 is divisible by 1 .so the number of lucky pairs are 2.

Given two boolean values

isGrassTrimmerFound and isWaterHosePipeFound as inputs, create three JS promises using async/await and try/catch blocks.

Input

The first line of input contains a boolean isGrassTrimmerFound

The second line of input contains a boolean isWaterHosePipeFound

Sample Input 1

true

true

Sample Output 1

Grass Trimmed

Garden Cleaned

Watered Plants

Sample Input 2

true

false

Sample Output 2

Grass Trimmed

Garden Cleaned

Water Hose Pipe Not Found

"use strict";

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

function main() {

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

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

 /* Write code */

 const myPromise = async () => {

  try {  

   /* Write code */

  } catch(error) {

   /* Write code */
