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… WebJul 7, 2024 · Binary search is a common algorithm used in programming languages and programs.
