What is a Tree? A Tree is a hierarchical data structure composed of nodes connected by edges. It has a root node and zero or more subtrees, each with its own subtree structure. Unlike arrays or linked lists, trees are non-linear, offering a more diversified set of use-cases. Structure of a Tree Example: Types of […]
A Dynamic Array is an array data structure that automatically resizes itself when it reaches capacity. Unlike static arrays, which have a fixed size, dynamic arrays can grow or shrink as needed. Why Use Dynamic Arrays? Java Implementation Here is a simple implementation of a dynamic array in Java: Dynamic arrays are versatile and easy
A Doubly Linked List (DLL) is a data structure consisting of a sequence of elements, called “nodes,” where each node points to both its next and previous nodes.

A Linked List is a data structure used for storing collections of data. Unlike an array, which stores data contiguously in memory, a Linked List stores references to its elements. A single element in a Linked List, typically called a “node,” holds both the data and a reference (or “link”) to the next node in
A stack is a last-in-first-out (LIFO) data structure. This means that the last element added to the stack is the first element removed.
One of the most basic yet powerful data structures you’ll come across is the Array. This guide will give you a clear understanding of arrays, their importance, and how to use them. What’s an Array? An array is a collection of items, usually of the same type, stored in contiguous memory locations. It is a
A data structure is a particular way of organizing data in a computer memory so that it can be used efficiently.
