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. philips domestic appliances hillhouseWebSep 20, 2024 · Binary search Binary search is a search strategy based on divide and conquer. The method divides the list into two halves at each step and checks weather the element to be searched is on the top or lower side of the array.
