How do you tell if an integer is a power of 2?
If log2(n) is integer than n is a power of 2, else not. Keep dividing the number by two, i.e, do n = n/2 iteratively until n becomes 1. In any iteration, if n%2 becomes non-zero and n is not 1 then n is not a power of 2. If n becomes 1 then it is a power of 2.
