"WebMeta Binary Search is a one-sided binary search where we work on the index using bit manipulation. We are to find the target index by using bit manipulation like the below example where the algorithm is explained. Say the input array is [3, 4, 6, 8, 12, 14, 16] and searching key says 14. The idea is to figure out the target index. " - Binary search edge cases
