    201 - Bitwise AND of Numbers Range.

    Medium

    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:

    • <code>0 <= left <= right <= 2<sup>31</sup> - 1</code>
