本文介绍了一种方法，用于反转一个给定32位无符号整数的所有位。例如，输入43261596(二进制00000010100101000001111010011100)，输出964176192(二进制00111001011110000010100101000000)。此外，讨论了当此函数被频繁调用时的优化方案。

Reverse bits of a given 32 bits unsigned integer.

For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as00111001011110000010100101000000).

Follow up:
If this function is called many times, how would you optimize it?
