A Binary Search Tree (BST) is a special type of binary tree where each node follows a strict ordering property: the left child contains values less than the parent node, and the right child contains values greater than the parent node. BSTs allow efficient searching, insertion, and deletion operations, making them fundamental in algorithms requiring […]

Level order traversal is a method of visiting nodes in a binary tree level by level from top to bottom and from left to right. It uses a queue to keep track of nodes that need to be visited. This traversal is also called Breadth-First Traversal (BFS) because it explores each level fully before moving

Counting the total number of nodes in a binary tree is a fundamental operation in tree data structures. It helps in understanding the size of the tree, which is useful for performance analysis and in algorithms that require tree metrics. Both recursive and iterative methods can be used to count nodes efficiently. Understanding the Problem

Deleting a node from a binary tree involves removing a specified node while maintaining the structure of the tree. Unlike binary search trees, where specific rules help maintain ordering, general binary tree deletion may replace the node with the deepest rightmost node. Understanding deletion is essential for memory management and maintaining proper tree structure. Understanding

The height of a binary tree is a fundamental property representing the maximum depth from the root to a leaf node. While recursion is the most common approach to calculate height, an iterative approach using a queue can achieve the same result. Having both methods allows programmers to choose based on their requirements or memory

Inorder traversal is a method of visiting all nodes in a binary tree by visiting the left subtree first, then the root node, and finally the right subtree. This traversal method is especially important for binary search trees because it prints the nodes in ascending order. Understanding inorder traversal is crucial for operations like sorting,

Preorder traversal is a method of visiting all nodes in a binary tree by first visiting the root node, then the left subtree, and finally the right subtree. This traversal is often used for copying a tree, creating prefix expressions, or saving tree structures. Understanding preorder traversal is essential for many tree-based algorithms and applications.

Postorder traversal is a method of visiting all nodes in a binary tree by first traversing the left subtree, then the right subtree, and finally the root node. This traversal is useful for deleting trees, evaluating postfix expressions, and performing bottom-up computations. Understanding postorder traversal is essential for tasks that require processing child nodes before

A binary tree is a hierarchical data structure in which each node has at most two children: a left child and a right child. Binary trees are widely used in applications such as expression parsing, searching, and sorting because they allow efficient data organization. Understanding binary trees is fundamental to mastering more complex structures like

A circular linked list is a variation of a linked list where the last node points back to the first node, forming a closed loop. This allows continuous traversal from any node, which is useful in applications like round-robin scheduling, CPU task management, and buffering. Mastering circular linked lists is essential for implementing operations that
