Solution in JavaScript (Node.js 12.16.1) (judge verdict: Accepted)

function Main(input) {
	input = input.split("\n");
	//文字列から10進数に変換するときはparseIntを使います
	var x = parseInt(input[0], 10);
	//出力
	console.log('%d', x == 0 ? 1 : 0);
}
//*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"));
