Chapter: AVL Trees – Balanced Binary Search Trees An AVL Tree is a self-balancing Binary Search Tree (BST) where the difference between heights of left and right subtrees (called the Balance Factor) is strictly maintained. The AVL Tree, named after…
Tree traversal is a foundational concept in computer science and is widely studied in the curriculum of B.Tech and BCA programs. It refers to the systematic method of visiting every node in a tree data structure, exactly once, in a…
In the domain of data structures, binary trees represent one of the most foundational and versatile non-linear structures. A binary tree is a tree data structure where each node has at most two children, typically referred to as the left…
A binary tree is a fundamental hierarchical data structure in computer science and plays a critical role in many advanced algorithms and real-world applications. In the context of B.Tech Data Structures Notes 2025, it is considered a core component of…
Infix to Postfix conversion is a critical concept in Unit 2 Notes Data Structures, forming the foundation for understanding expression evaluation, compiler design, and data structure manipulation using stacks. This topic plays a vital role in simplifying mathematical expression processing…
n the study of data structures for B.Tech and BCA students, the concept of memory allocation forms a foundational pillar. Efficient memory allocation ensures optimal utilization of system resources and directly impacts the performance of any software application. This chapter…
A Circular Linked List (CLL) is a variation of the traditional linked list in which the last node does not point to NULL but rather links back to the first node, thus forming a circle. This circular nature allows for…
A Doubly Linked List (DLL) is a type of linear data structure where each element is represented as a node that contains three parts: a pointer to the previous node, the data field, and a pointer to the next node.…
In the context of B.Tech Data Structures Notes 2025, representing a polynomial using arrays is often considered the simplest approach. However, this approach has limitations, especially when dealing with sparse polynomials or operations like insertion and deletion of terms. A…
A linked list is a linear data structure where elements are stored in nodes and each node points to the next node using a pointer. Unlike arrays, linked lists do not require contiguous memory locations. Each node contains two parts:…
