In the above tree to delete node 6 with two children, we first find the inorder successor for that node to be deleted. We find the in-order successor by finding the minimum value in the right subtree. In the above case, the minimum value is 7 in the right subtree. We copy it to ...

Binary Search Tree (BST) Implementation In Java The following program in Java provides a demonstration of all the above BST operation using the same tree used in illustration as an example. class BST_class { //node class that defines BST node ...
There are two searching algorithms implemented in the CSimpleBinaryTree class. A linear search and a binary search. The linear search is used up to the point when the number of items in the tree exceeds the threshold switching value (default is 10), thereafter the searching is done using th...
Let us see the following implementation to get a better understanding − Live Demo #include <bits/stdc++.h> using namespace std; class Solution { public: int numTrees(int n) { vector <int> dp(n+1); dp[0] = 1; for(int i =1;i<=n;i++){ for(int j = 0;j<i;j++){ //...
classBinaryTree { staticNode head; /* Given a binary search tree and a number, inserts a new node with the given number in the correct place in the tree. Returns the new root pointer which the caller should then use (the standard trick to avoid using reference ...
So tell you what, anyone who is interested, read the wikipedia page on AVL tree balancing, and next time on FAIC I'll post an implementation of an immutable height-balanced AVL tree which implements the contract above. (This is pretty straightforward stuff; the immutable queue was ...
