Given two integers left
and right
that represent the range [left, right]
, return the bitwise AND of all numbers in this range, inclusive.
Example 1:
Input: left = 5, right = 7 Output: 4
Example 2:
Input: left = 0, right = 0 Output: 0
Example 3:
Input: left = 1, right = 2147483647 Output: 0
Constraints:
0 <= left <= right <= 231 - 1
