Binary search algorithm worst case
WebMay 10, 2024 · 2. The first or last element will give the worst case complexity in binary search as you'll have to do maximum no of comparisons. Example: 1 2 3 4 5 6 7 8 9. … WebWorst Case Complexity - In Binary search, the worst case occurs, when we have to keep reducing the search space till it has only one element. The worst-case time complexity of Binary search is O (logn). 2. Space …

WebData Structures and Algorithms: Arrays, Lists, Linked Lists, Stack, Binary Tree, Binary Search Trees and their Time/Space Complexities for worst and average cases Platforms: Visual Studio ... 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.
