How can I determine that a positive integer has exactly one zero in its binary representation?
Okay, that's helpful. But how can I do this quickly without converting the integer into binary?
One trick you can use is to check if the integer is a power of 2. If it is, then it has only one bit set to 1 in its binary representation, which means it has exactly one zero. Another way is to use the bitwise AND operation with the integer and its predecessor. If the result is 0, then the integer has exactly one zero in its binary representation.
