C Program to Perform Deletion in Binary Search Tree

WebThis is a C Program to perform deletion in binary search tree. The important thing to note is, inorder successor is needed only when right child is not empty. In this particular case, inorder successor can be obtained by finding the minimum value in right child of the node. Here is source code of the C Program to Perform Deletion in a BST. WebQuestion. You are implementing a binary tree class from scratch which, in addition to insert, find, and delete, has a method getRandomNode () which returns a random node from the tree. All nodes should be equally likely to be chosen. Design and implement an algorithm for getRandomNode, and explain how you would implement the rest of the methods.
