Reverse Bits of an Integer

Given a 32-bit unsigned integer, reverse its bits and return the resulting integer. You need to consider that the input integer may vary between 0 and 4294967295. For example: Input: 43261596 Output: 964176192 Explanation: The binary representation of 43261596 is 00000010100101000001111010011100, which reversed is 00111001011110000010100101000000 (equivalent to 964176192).
