[Solved] Power of two failed to pass the test

by


Are you sure that you are checking power of 2? Rather, being checked divisible with 2. If you are serious, use the piece of cake snippet

return n > 0 && ((n & -n) == n);

The second way,

enter image description here

private static boolean powerOf2(int num)
{
  if(num <= 0){
   return false;
  }

  while(num > 1)
  {
   if(num % 2 != 0)
   {
    return false;
   }
   num = num / 2;
  }
  return true;
}
