Leetcode 201 Bitwise AND of Numbers Range solution in c++ | Hindi Coding Community

 

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

class Solution {

public:

    int rangeBitwiseAnd(int left, int right) {

        long ans=left;

        for(long i=left; i<=right; i++) {

            ans &= i;

            if(ans==0) return 0;

        }

        return ans;

    }

};
