<span style="color:#323232;">private bool isEven(int num) {
</span><span style="color:#323232;">if (num == 0) return true;
</span><span style="color:#323232;">if (num == 1) return false;
</span><span style="color:#323232;">if (num ＜ 0) return isEven(-1 * num);
</span><span style="color:#323232;">return isEven(num - 2);
