Jul 23, 2025 · Graph Data Structure is a collection of nodes connected by edges. It's used to represent relationships between different entities. If you are looking for topic-wise list of problems on different …

A graph data structure consists of a finite (and possibly mutable) set of vertices (also called nodes or points), together with a set of unordered pairs of these vertices for an undirected graph or a set of …

Graphs are non-linear because the data structure allows us to have different paths to get from one vertex to another, unlike with linear data structures like Arrays or Linked Lists.

Choosing the right data structure for a given problem is important for optimizing the time and space complexity of algorithms. This tutorial will explore different data structures used to represent graphs, …

Jun 29, 2024 · One of the most important things to understand in graph theory is how to store them in memory. In this tutorial, we’ll explain and compare three main data structures for graphs and show …

In this tutorial, you will understand different representations of graph.

Sep 1, 2025 · What Are Graphs in Data Structure? Graphs in data structures are non-linear data structures made up of a finite number of nodes or vertices and the edges that connect them.

Nov 25, 2025 · Understand Graph Data Structure, its types, uses, examples, and algorithms in this tutorial. Learn how to implement and optimize graph-based solutions here.

Graphs are perhaps the most versatile data structure addressed in this book. As discussed in chapter 8, graphs at their simplest are just nodes and edges, with nodes representing things and the edges …

Nov 24, 2025 · A graph is a non-linear data structure made up of vertices (nodes) and edges (connections) that represent relationships between objects. Unlike arrays or linked lists, graphs do …
