What data structure is used for graphs?

A graph can be represented using 3 data structures- adjacency matrix, adjacency list and adjacency set. An adjacency matrix can be thought of as a table with rows and columns. The row labels and column labels represent the nodes of a graph.

What is graph ADT?

The graph abstract data type (ADT) is defined as follows: Graph() creates a new, empty graph. addVertex(vert) adds an instance of Vertex to the graph. addEdge(fromVert, toVert) Adds a new, directed edge to the graph that connects two vertices.

What is graph and types of graph in data structure?

A graph is a non-linear kind of data structure made up of nodes or vertices and edges. The edges connect any two nodes in the graph, and the nodes are also known as vertices.

What are 4 types of graphs?

There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs.

What is linear data structure?

A Linear data structure have data elements arranged in sequential manner and each member element is connected to its previous and next element. This connection helps to traverse a linear data structure in a single level and in single run. Such data structures are easy to implement as computer memory is also sequential.

What is queue and stack?

Stack is a container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. Queue is a container of objects (a linear collection) that are inserted and removed according to the first-in first-out (FIFO) principle.

Why DFS is used?

Using DFS we can find path between two given vertices u and v. We can perform topological sorting is used to scheduling jobs from given dependencies among jobs. Topological sorting can be done using DFS algorithm. Using DFS, we can find strongly connected components of a graph.

What is MST in graph?

A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight.

What is tree ADT?

a tree is a widely used abstract data type (ADT) or data structure implementing this ADT that simulates a hierarchical tree structure, with a root value and subtrees of children, represented as a set of linked nodes.

How many types of data structure are there?

Basically, data structures are divided into two categories:

  • Linear data structure.
  • Non-linear data structure.
