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.

"WebThe Binary Search Algorithm There is one thing to note before starting, the algorithm requires that the given list should be sorted. This is because we can find if a number is after or before a certain another number in a list based on the list’s sorting. Recall how we find words in a dictionary or page numbers in a book.
