• The first line of input contains a number firstNumber
• The second line of input contains a number secondNumber

• The first line of output should contain the ratio of firstNumber and secondNumber
• The second line of output should contain the sum of cubes of firstNumber and secondNumber
• The third line of output should contain the product of squares of firstNumber and secondNumber

i want code in between write code here

"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 ArithmeticOperations(firstNumber, secondNumber) {

 this.firstNumber = firstNumber;

 this.secondNumber = secondNumber;

}

function main() {

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

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

 const operation1 = new ArithmeticOperations(firstNumber, secondNumber);

 /* Write your code here */

 console.log(operation1.ratioOfNumbers());

 console.log(operation1.sumOfCubesOfNumbers());

 console.log(operation1.productOfSquaresOfNumbers());
