Binary search algorithm worst case

WebThe worst case of Binary Search occurs when: The element is to search is in the first index or last index In this case, the total number of comparisons required is logN … WebThe worst-case situation will occur when we reach the base case (unsuccessful search), i.e., n -> n/2 -> n/4 -> ... 1 -> unsuccessful search. Suppose we reach the base case after k number of steps => n/2^k = 1 => n = 2^k => k = log2n. In simple words, after log2nnumber of steps, the algorithm will reach its base case.
