A weighted Graph is a Graph where the edges have values. The weight value of an edge can represent things like distance, capacity, time, or probability. A connected Graph is when all the vertices are connected through edges somehow. A Graph that is not connected, is a Graph with isolated (disjoint) subgraphs, or single isolated vertices.

Graph is a non-linear data structure consisting of a finite set of vertices (or nodes) and a set of edges (or links)that connect a pair of nodes. Graphs are widely used to represent relationships between entities. ... DSA (Data Structures and Algorithms) is the study of organizing data efficiently using data structures like arrays, stacks, and ...
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 vertices, and the links that connect the vertices are called edges.. Formally, a graph is a pair of sets (V, E), where V is the set of vertices and E is the set of edges, connecting the pairs of ...
The repository aims to provide a comprehensive collection of DSA sheets that cover various topics related to programming, data structures, and algorithms. These sheets are designed to help students and developers learn and practice programming skills to prepare for interviews, competitive coding, and real-world software development.
Mastering DSA enables developers to write optimized code that performs well even with large datasets. The very first step in the journey is the selection of a complete roadmap. ... Finally, challenge yourself with advanced DSA topics like dynamic programming and graph algorithms, solving complex problems to refine your skills and prepare for ...
Graph Terminology. Adjacency: A vertex is said to be adjacent to another vertex if there is an edge connecting them.Vertices 2 and 3 are not adjacent because there is no edge between them. Path: A sequence of edges that allows you to go from vertex A to vertex B is called a path. 0-1, 1-2 and 0-2 are paths from vertex 0 to vertex 2.; Directed Graph: A graph in which an edge (u,v) doesn't ...
Line 60: The DFS traversal starts when the dfs() method is called. Line 33: The visited array is first set to false for all vertices, because no vertices are visited yet at this point. Line 35: The visited array is sent as an argument to the dfs_util() method. When the visited array is sent as an argument like this, it is actually just a reference to the visited array that is sent to the dfs ...

Graphs • A graph is a formalism for representing relationships among items – Very general definition because very general concept • A graph is a pair G = (V,E) – A set of vertices, also known as nodes V = {v 1,v 2,…,v n} – A set of edges E = {e 1,e 2,…,e m} • Each edge e i is a pair of vertices (v j,v k)
Undirected Graph: If the edges of the do not have any direction associated with them, it is called an undirected graph. Based on the weights of edges, a graph can also be classified into two categories: Weighted Graph: If the edges of the graph have some weight assigned to them, it is called a weighted graph.
Graphs provide the ultimate in data structure flexibility. A graph consists of a set of nodes, and a set of edges where an edge connects two nodes. Trees and lists can be viewed as special cases of graphs. Graphs are used to model both real-world systems and abstract problems, and are the data structure of choice in many applications.
