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.

WebSep 27, 2024 · The Binary Search algorithm works as follows: Set the search space equal to the sorted array Take the middle element of the search space and compare it to the target value. - If the target equals the middle element, you have found the target value. Return the index of the middle element and terminate the function.
WebA binary search works like this: Start by setting the counter to the middle position in the list. If the value held there is a match, the search ends.
