Given a tree, and the cost of a subtree is defined as |S|*AND(S) where |S| is the size of the subtree and AND(S) is bitwise… Read More
There are n nodes and m bridges in between these nodes. Print the possible path through each node using each edges (if possible), traveling through… Read More
If the DFS finishing time f[u] > f[v] for two vertices u and v in a directed graph G, and u and v are in… Read More
Is following statement true/false? A DFS of a directed graph always produces the same number of tree edges, i.e., independent of the order in which… Read More
Is following statement true/false If a DFS of a directed graph contains a back edge, any other DFS of the same graph will also contain… Read More
Which of the following condition is sufficient to detect cycle in a directed graph? (A) There is an edge from currently being visited node to… Read More
Given two vertices in a graph s and t, which of the two traversals (BFS and DFS) can be used to find if there is… Read More
Make is a utility that automatically builds executable programs and libraries from source code by reading files called makefiles which specify how to derive the… Read More
Consider the following graph, Among the following sequences: (I) a b e g h f (II) a b f e h g (III) a b… Read More
Let G be an undirected graph. Consider a depth-first traversal of G, and let T be the resulting depth-first search tree. Let u be a… Read More
The Breadth First Search algorithm has been implemented using the queue data structure. One possible order of visiting the nodes of the following graph is… Read More
What are the appropriate data structures for following algorithms? 1) Breadth First Search                        … Read More
Traversal of a graph is different from tree because (A) There can be a loop in graph so we must maintain a visited flag for… Read More
