Trees Definitions: Binary Tree: A binary tree is either empty or it consists of a node called the root together with two binary trees called the left subtree and the right subtree of the root. Node: Each element of a binary tree is called a node of a tree. Father: If A is the root […]
Threaded Binary Trees Threaded Binary Trees are an improvement over Binary Search Trees that uses stack for iterative traversal. If a strategy is introduced such that the leaf node of a binary search tree points to its inorder predecessor or its successor, then direct links (called threads) are obtained to traverse a tree without using […]

Binary Search Trees: A Binary Search Tree is a Binary Tree which satisfies the following conditions: The left subtree of the root contains keys smaller than the root. The right subtree of the root contains keys greater than the root. The left and right subtrees are also Binary Search Trees. There are no duplicates in […]

Advanced Trees Definitions: Red/Black Tree: It was invented by Rudolf Bayer in 1972. Red-black trees are one of the preferred methods of maintaining binary search trees. An n node red-black tree has the height of O(logn). Moreover balancing time for such a tree on account of insertion and deletion is O(logn). A red-black tree is […]
