Examples: Example 1: Input: n=5 ,k=0 Output: Yes Explanation: … WebThis one is simplest, since if any bit in a number (except for the sign) is one, the number itself cannot be zero. Assuming you're working in a programming language where any non-zero number is considered true, you can simply write if (number) which will be true if any bit is one. You can also write if (!!number) B.
