Please fill the code in "write your code here"

They were just sample outputs. There are other test cases too which should be passed

Answer 1

"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().replace(/'/g, '"'));

  console.log(myArray.every((idx) => {
    return typeof this[idx] === 'string';
  }))
}
