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++];
}


function main() {
  const myArray = JSON.parse(readLine().replace(/'/g, '"'));
 // Write your code here
  let newArray = myArray.map(function(data) {
    if (typeof data != 'number') {
      return typeof data;
    }
    else {
      return data * 2;
    }
  });
  console.log(newArray)
}
