Leetcode 190. Reverse bits (reverse number of bits)

Reverse bits of a given the unsigned integer.

For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 ( Represented in binary as 00111001011110000010100101000000).

followup: What would you optimize it when this function is called many times?
