A Binary search tree (referred to as BST hereafter) is a type of binary tree. It can also be defined as a node-based binary tree. BST is also referred to as ‘Ordered Binary Tree’. In BST, all the nodes in the left subtree have values that are less than the value of the root ...
The binary search tree and AVL tree are binary trees that impose restrictions on the insertion/deletion behaviors. In-order, pre-order and post-order traversals aren’t just important only for the binary tree; if you’re processing data in any tree, you’ll use these traversals regularly....
For example, let's try to delete 12, 20, and 9 from the following tree. Deleting 12 from the Binary Search Tree Deleting 20 from Binary Search Tree: Deleting 9 from Binary Search Tree: Traversing in Binary Search Tree We can traverse a binary search tree in two different ways. Let's ...
Binary tree (a) has 8 nodes, with node 1 as its root. Node 1's left child is node 2; node 1's right child is node 3. Notice that a node doesn't need to have both a left child and right child. In binary tree (a), node 4, for example, has only a right child. Further...

Let x be a node in a binary search tree. If y is a node in the left subtree of x, then y.key≤x.key. If y is a node in the right subtree of x, then x.key≤y.key. The following figure shows an example of the binary search tree. ...
