    They call me a StackOverflow expert:

    private bool isEven(int num) {
if (num == 0) return true;
if (num == 1) return false;
if (num ＜ 0) return isEven(-1 * num);
return isEven(num - 2);
}

      StackoverflowException.

      What do I do now?

      Nvm. Got it.

        if(num % 2 == 0){
       int num1 = num/2
       int num2 = num/2
       return isEven(num1) && isEven(num2)   
  } 

if(num % 3 == 0){
      int num1 = num/3
      int num2 = num/3
      int num3 = num/3
      return isEven(num1) && isEven(num2) && isEven(num3) 
}

      Obviously we need to check each part of the division to make sure if they are even or not. /s
