WebBinary search does not use the values of the elements. It uses the indices of the elements. In a list of ten elements, numbered from 0 to 9, the midpoint is around 4.5. Since that is not an integer element index, either 4 or 5 is used. When there are only two elements left, either one may be used as the midpoint. – 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.
