·        + Boolean addItem(item)

·        + Boolean addItemAt(index, item)

·        + Object removeItemAt(index)

·        + Object removeItem(index, item)

·        + Object deleteItemIfOdd(item)

·        + Boolean isEmpty()

·        + Boolean isFull()

·        + Object getItemAt(index)

Find the Duplicate in the array

Given an myArray write a JS program to find duplicate in the Array.

input1

[1,2,3,4,5,7,7,8]

output1

7

input1

{'light'', "dark", "twinlight"]

output2

false

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

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

/* Write your code here */

}
