In this article, we are going to learn how to search an element from an array using binary_search() function of C++ Standard Template Library (STL)?
<< endl; v[2] = 10; result = binary_search(v.begin(), v.end(), 3); if (result == false) cout << "Element 3 doesn't exist in vector." << endl; return 0; }Let us compile and run the above program, this will produce the following result −Element...
Two elements of a binary search tree (BST) are swapped by mistake. Recover the tree without changing its structure. Note: A solution using O(n) space is pretty straight forward. Could you devise a constant space solution? confused what"{1,#,2,3}"means?> read more on how binary tree ...
We will be given a Binary Search Tree and we have to create a C++ program which counts the total number of leaf nodes present in it using recursion. Aleaf nodeis one which has no child. It is also known asinternal node. Expected Input and Output ...
