    "use strict";


process.stdin.resume();


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());


   const deep_Map=(input,callback)=>input.map(entry=>entry.map?deep_Map(entry,callback):callback(entry))
   squaresArray=deep_Map(myArray,x=>x**2)
   console.log(JSON.stringify(squaresArray));
