A Binary Search is a searching technique used in C++ to search an element from an array. Binary function that accepts two arguments of the type pointed by ForwardIterator (and of type T), and returns a value convertible to bool. A binary Search Tree is a binary tree where the value of any node is greater than the left subtree and less than the right subtree. This means that each search iteration eliminates half of the remaining elements, allowing it to skip over large chunks of data very quickly. Then each iteration of the binary search cuts the search space in half, so the algorithm tests O (log N) O(logN) values. So let‘s get started! In C++, STL provide std::binary_search () function which implements binary search algorithm to check whether an element exists in the given sorted range. If target exists, then return its index.
