What's the simplest way to test whether a number is a power of 2 in C++?
...he numbers is 0 0 0 0 = 0.
Time complexity : O(1).
Approach #3:
Bitwise XOR the number with its just previous number should be sum of both numbers.
Example: Number = 8
Binary of 8: 1 0 0 0
Binary of 7: 0 1 1 1 and the bitwise XOR of both the numbers is 1 1 1 1 = 15.
Time complexity : O(1).

Zero-based month numbering [closed]
...m Assembly programmers. Instead of assigning 1 to the count register, they XOR'ed the register with itself, which was slightly faster in CPU cycles. This meant that counting would start with 0 and would always be up to the length of elements, excluding the last one.
Also, the use of zero is also po...
