Binary Search Algorithm with Example Code

In terms of the number of comparisons, the performance of binary search can be analyzed by viewing the run of the procedure on a binary tree. The root node of the tree is the middle element of the array. The middle element of the lower half is the left child node of the root, and the middle element of the upper half is the right child node of the root. The rest of the tree is built in a similar fashion. … WebIn this article, we will learn binary search algorithm. Binary search algorithm is used to search an element in a given set of elements.
