# binary tree insertion c++

#include Given a binary tree and a key, insert the key into the binary tree at the first position available in level order. case 3 : printf(“Pre-Order Traversal is:\n”); posttrav(root); if(root1->right!=NULL) Binary tree is one of the data structures that are efficient in insertion and searching operations. Also, the concepts behind a binary search tree are explained in the post Binary Search Tree. break; Difference between Call by Value and Call by Reference in C, Python Speech Recognition Using Google Speech API, C# Local Database – How to Connect and Use Local Database (Sql Server). return false; { we respect your privacy and take protecting it seriously.

A Binary Search Tree (BST) is a binary tree in which all the elements stored in the left subtree of node x are less then x and all elements stored in the right subtree of node x are greater then x.
