Ans. In Breadth first algorithm, all the adjacent nodes of the starting node is visited first and then the same rule is followed while moving inwards whereas In Depth first algorithm, all the nodes of a single traversal path are visited first till a cycle or an end is found. For example , given the following entries of adjacent nodes 1,2 1,3 1,6 2,4 2,5 3,6 The Breadth first path would be 1,2,3,6,4,5 and Depth first path would be 1,2,4,5,3,6
