Frequently Asked Questions(FAQs) on Graph Data Structure
1. What is a graph?
A graph is a data structure consisting of a set of vertices (nodes) and a set of edges that connect pairs of vertices.
2. What are the different types of Graph Data Structure?
Graph Data Structure can be classified into various types based on properties such as directionality of edges (directed or undirected), presence of cycles (acyclic or cyclic), and whether multiple edges between the same pair of vertices are allowed (simple or multigraph).
3. What are the applications of Graph Data Structure?
Graph Data Structure has numerous applications in various fields, including social networks, transportation networks, computer networks, recommendation systems, biology, chemistry, and more.
4. What is the difference between a directed graph and an undirected graph?
In an undirected graph, edges have no direction, meaning they represent symmetric relationships between vertices. In a directed graph (or digraph), edges have a direction, indicating a one-way relationship between vertices.
5. What is a weighted graph?
A weighted graph is a graph in which each edge is assigned a numerical weight or cost. These weights can represent distances, costs, or any other quantitative measure associated with the edges.
6. What is the degree of a vertex in a graph?
The degree of a vertex in a graph is the number of edges incident to that vertex. In a directed graph, the indegree of a vertex is the number of incoming edges, and the outdegree is the number of outgoing edges.
7. What is a path in a graph?
A path in a graph is a sequence of vertices connected by edges. The length of a path is the number of edges it contains.
8. What is a cycle in a graph?
A cycle in a graph is a path that starts and ends at the same vertex, traversing a sequence of distinct vertices and edges in between.
9. What are spanning trees and minimum spanning trees?
A spanning tree of a graph is a subgraph that is a tree and includes all the vertices of the original graph. A minimum spanning tree (MST) is a spanning tree with the minimum possible sum of edge weights.
10. What algorithms are commonly used to traverse or search Graph Data Structure?
Common graph traversal algorithms include depth-first search (DFS) and breadth-first search (BFS). These algorithms are used to explore or visit all vertices in a graph, typically starting from a specified vertex. Other algorithms, such as Dijkstra’s algorithm and Bellman-Ford algorithm, are used for shortest path finding.
