Worst Case, Average Case, and Best Case Aman Kharwal

Uniform binary search stores, instead of the lower and upper bounds, the difference in the index of the middle element from the current iteration to the next iteration. A lookup table containing the differences is computed beforehand. For example, if the array to be searched is [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11], the middle element () would be 6. In this case, the middle element of the left suba… WebSep 30, 2024 · In binary search, best-case complexity is O (1) where the element is found at the middle index. The worst-case complexity is O (log2n). Dry Run Let’s assume that we have an array of size 10,000. In a linear search, best-case complexity is O (1) and worst-case complexity is O (10000).
