Given two integers left and right that represent the range [left, right], return the bitwise AND of all numbers in this range, inclusive.

Examples

Example 1:

Input: left = 5, right = 7

Output: 4

Explanation: AND of 5 (101), 6 (110), 7 (111) = 100 = 4

Example 2:

Input: left = 0, right = 0

Output: 0

Example 3:

Input: left = 1, right = 2147483647

Output: 0

Constraints

  • 0 <= left <= right <= 2^31 - 1
