Connected Graph Property Explained With Simple Example

adminby admin

Graph is a data structure which consists of a set of vertices which is called as Node, together with a set of collection of pair of vertices which is called as an Edge.
A graph data structure can be represented as a pair (V, E) where V is a set of nodes called vertices and E is a collection of pairs of vertices called edges. Graphs are used to solve many real-life problems such as fastest ways to go from A to B etc.

A Graph is called connected graph if each of the vertices of the graph is connected from each of the other vertices which means there is a path available from any vertex to any other vertex in the Graph.

Depth first search for a Graph

adminby admin

Traversal of a Graph means visiting each and every nodes present in the Graph. Traversal can be done using various approaches and here we are going to talk about one of most famous and useful traversal algorithm known as Depth first search (DFS). In this algorithm, backtracking and recursion is being used along with a Stack to visit all the nodes. Before going ahead have a look into Graph Basics.
