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

const Main = (input) => {
  // 入力値の整形
  const TARGET_ARRAY = [7, 5, 3];

  if (TARGET_ARRAY.indexOf(Number(input)) >= 0) {
    console.log('YES');
  } else {
    console.log('NO');
  }
};

//* 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'));
