       "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())
            /* Write your code here and log the output */
            let res = [];


            myArray.forEach(item => {
                if (typeof item === 'number') {
                    res.push(item ** 2);
                } else {
                    let arr = [];


                    if (item.length < 2) {
                        arr.push(item ** 2);
                    } else {
                        item.forEach(n => arr.push(n ** 2));
                    }


                    res.push(arr);
                }
            })


            console.log(res);
        }
