%description
It is used to travel graphs, by using DFS and BFS to get the path from
node to each leaf node. Depth first traversal(DFS) is a recursive
algorithm for searching all the vertices of a graph or tree data
structure. Traversal means visiting all the nodes of a graph. Breadth
first traversal(BFS) algorithm is used to search a tree or graph data
structure for a node that meets a set of criteria. It starts at the tree’s
root or graph and searches/visits all nodes at the current depth level
before moving on to the nodes at the next depth level. Also, it provides
the matrix which is reachable between each node. Implement reference about
