A graph is a data structure that consists of the following two components: 1. A finite set of vertices also called as nodes. 2. A finite set… Read More
Breadth-First Traversal (or Search) for a graph is similar to Breadth-First Traversal of a tree (See method 2 of this post). The only catch… Read More
Depth First Traversal (or Search) for a graph is similar to Depth First Traversal of a tree. The only catch here is, unlike trees,… Read More
