Solution in JavaScript (node.js v5.12) (judge verdict: Wrong Answer)

// inputに入力データ全体が入る
function Main(input) {
  	var inputLength = input.length;
  	var tmp = [];
  	while (inputLength > 0) {
      tmp.push("x");
      inputLength -= 1;
    }
  	console.log(tmp.join(""));
}
//*この行以降は編集しないでください（標準入出力から一度に読み込み、Mainを呼び出します）
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
