In this article, we are going to see C++ STL function binary_search() which uses the standard binary search algorithm to search an element within a range.
Binary Search Algorithm: In this tutorial, we will learn about the binary search algorithm, and it's time complexity in detail and then, implemented it in both C & C++.
