1/**
2 * [201] Bitwise AND of Numbers Range
3 *
4 * Given two integers left and right that represent the range [left, right], return the bitwise AND of all numbers in this range, inclusive.
5 *  
6 * Example 1:
7 * 
8 * Input: left = 5, right = 7
9 * Output: 4
10 * 
11 * Example 2:
12 * 
13 * Input: left = 0, right = 0
14 * Output: 0
15 * 
16 * Example 3:
17 * 
18 * Input: left = 1, right = 2147483647
19 * Output: 0
20 * 
21 *  
22 * Constraints:
23 * 
24 * 	0 <= left <= right <= 2^31 - 1
25 *
