TODO 0190. Reverse Bits   easy

Reverse bits of a given 32 bits signed integer.

Example 1:

Input: n = 43261596

Output: 964176192

Explanation:

Integer Binary

Example 2:

Input: n = 2147483644

Output: 1073741822

Explanation:

Constraints:

  • 0 <= n <= 2^{31} - 2
  • n is even.

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