WebJan 11, 2024 · So, the time complexity will be O(logN). The Worst Case occurs when the target element is not in the list or it is away from the middle element. So, the time complexity will be O(logN). How to Calculate Time Complexity: Let's say the iteration in Binary Search terminates after k iterations. At each iteration, the array is divided by half. WebMay 23, 2011 · The recurrence relation of binary search is (in the worst case) T (n) = T (n/2) + O (1) Using Master's theorem n is the size of the problem. a is the number of subproblems in the recursion. n/b is the size of each subproblem. (Here it is assumed that all subproblems are essentially the same size.)
