Bitwise AND of a Range
Advanced
Return the bitwise AND of every number from left to right (both included).
The starter code ands the numbers one by one. It is correct but far too slow for big ranges.
Examples
Example 1
Input:
and_of_range(5, 7)
Output:
4
Example 2
Input:
and_of_range(0, 0)
Output:
0
Constraints
0 <= left <= right < 2**31
