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.

What is a Graph? A graph is an abstract data type (ADT) which consists of a set of objects that are connected to each other via links. The interconnected objects are represented by points termed as …

A graph is a non-linear data structure that consists of a set of vertices (or nodes) and a set of edges that connect them. Unlike a tree, which has a hierarchical structure, a graph can have any number of …

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

What is the Data Structure? The common queries (e.g., “is (u,v) an edge?” versus “what are the neighbors of node u?”) Best for sparse or dense graphs? How will the adjacency matrix vary for an …

Nov 25, 2025 · Let’s learn everything about graphs in data structure, types, representation, traversal, implementation, and more. What is Graph Data Structure? A graph in data structure is a way to show …

Formally, a graph G is defined as a pair (V, E), where V represents the set of vertices or nodes, and E represents the set of edges connecting these nodes. In computer science and mathematics, the …

Jul 23, 2025 · Graph is a non-linear data structure like tree data structure. The limitation of tree is, it can only represent hierarchical data. For situations where nodes or vertices are randomly connected with …
