WebBinary Search. Time Complexity: O(log n) – Space Complexity O(1) Binary search is a divide and conquer searching algorithm that can only be performed on a sorted list.. Each iteration through the algorithm the middle item of the array is checked to see if it is a match, it it is the index is returned, otherwise half the array is disregarded and the remaining … WebThe key idea is that when binary search makes an incorrect guess, the portion of the array that contains reasonable guesses is reduced by at least half. If the reasonable portion had 32 elements, then an incorrect guess cuts it down to have at most 16. Binary search halves the size of the reasonable portion upon every incorrect guess.

We use big-O notation for asymptotic upper bounds, since it bounds the growth of the running time from above for large enough input sizes. Now we have a way to characterize the running time of binary search in all cases. We can say that the running time of binary search is always O (\log_2 n) O(log2 n).
