concatenate and remove Duplicates

Given two arrays arr1 and arr2 of positive integers write a JS program to concatenate two rows and remove duplicates from the concatenated array. Log the array with unique items in ascending order

input1

[1,4,7,3,7,3,3]

[2,4,5,5,3,2,1]

output1

[1,2,3,4,5,7]

"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++];

}

function main() {

 let arr1 = JSON.parse(readLine());

 let arr2 = JSON.parse(readLine());

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

 /* Write your code here and log the output */

}

The function accepts two positive integers ‘r’ and ‘unit’ and a positive integer array ‘arr’ of size ‘n’ as its argument ‘r’ represents the number of rats present in an area, ‘unit’ is the amount of food each rat consumes and each ith element of array ‘arr’ represents the amount of food present in ‘i+1’ house number, where 0 <= i

Common arrays in three arrays

given three arrays arr1,arr2,arr3 write a JS program to find the common items in the among three arrays.

sample input1

[1,2,3,'cat']

[1,'cat',4]

[1,'cat,64]

output1

[1,'cat']

sample input2

['cat','rat','dog']

['lion','fox']

['kiwi','eagle']

output2

[]

function readLine() {

 return inputString[currentLine++];

}

function main() {

 let arr1 = JSON.parse(readLine().replace(/'/g, '"'));

 let arr2 = JSON.parse(readLine().replace(/'/g, '"'));

 let arr3 = JSON.parse(readLine().replace(/'/g, '"'));

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

 /* Write your code here */

}

Cumulative Sum

given an array integers, write a JS program to get the cumulative sum of the items in the array

sample input1

[1, 10, 100, 1000]

sample output1

[1, 11, 111, 1111]

"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++];

}

function main() {

 let integers = JSON.parse(readLine());

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

 /* Write your code here */

}

Create a class Employee with basic_sal as its data member. Write a program to calculate the gross pay of an employee, with the allowances provided below.

Dearness Allowance = 21% of the Basic Pay

House Rent Allowance = 12% of Basic Pay

Provident Fund = 6.45% of Basic Pay

Net Pay = Basic Pay + Dearness Allowance + House Rent Allowance

Gross Pay = Net Pay − Provident Fund

Implement the program using the concept of Single Inheritance

Please someone help me with this program i am too frustrated solving this
