Right most set bit mask

WebThe task is to complete the function posOfRightMostDiffBit() which takes two arguments m and n and returns the position of first different bits in m and n. If both m and n are the same then return -1 in this case. Expected Time Complexity: O (max (log m, log n)). Expected Auxiliary Space: O (1). Constraints: 0 <= M <= 109 0 <= N <= 109 WebFeb 15, 2024 · Given a binary string S of length N, such that all 1s appear on the right. The task is to return the index of the first set bit found from the left side else return -1. Examples: Input: s = 00011, N = 5 Output: 3 Explanation: The first set bit from the left side is at index 3. Input: s = 0000, N = 4 Output: -1
