How can I determine that a positive integer has exactly one zero in its binary representation?
That's very clever! Can you show me an example using the bitwise AND operation?
Sure! Let's take the positive integer 12. In binary, 12 is represented as 1100, and its predecessor (i.e., the positive integer before it) is 11, which is represented as 1011. When we perform bitwise AND operation between 12 and 11, we get 1000, which is not equal to 0. Therefore, 12 doesn't have exactly one zero in its binary representation.
