3. The indegree of a vertex u is the number of incoming edges into u, .e, edges of the form (v,u) for some vertex v Consider the following algorithm that takes the adjacency list Alvi, v2, n] of a directed graph G as input and outputs an array containing all indegrees. An adjacency list Alvi, v.. /n] is an array indexed by the vertices in the graph. Each entry Alv, contains the list of neighbors of v) procedure Indegree(Alvi, v2,......

For a directed graph the in-degree of a vertex is the number of edges it has coming in to it, and the out- degree is the number of edges it has coming out. (a) Let G[i,j] be the adjacency matrix representation of a directed graph, write pseudocode (in the same detail as the text book) to compute the in-degree and out-degree of every vertex in the Page 1 of 2 CSC 375 Homework 3 Spring 2020 directed graph.

Let G (V, E) be a directed graph with n vertices and m edges. It is known that in dfsTrace of G the function dfs is called n times, once for each vertex It is also seen that dfs contains a loop whose body gets executed while visiting v once for each vertex w adjacent to v; that is the body gets executed once for each edge (v, w). In the worst case there are n adjacent vertices. What do...

Viterbi algorithm We can use dynamic programming on a directed graph G = (V, E) for speech recognition. Each edge (u, v) in E is labeled with a sound s(u, v) from a finite set S of sounds. The labeled graph is a formal model of a person speaking a restricted language. Each path in the graph starting from a distinguished vertex v0 in V corresponds to a possible sequence of sounds produced by the model. The label of a...

Give an efficient algorithm that takes a directed graph G = (V, E) and two vertices u, v E V, and determines if there are at least two edge-disjoint paths in G from u to v. i.e., your algorithm should determine whether there are at least two paths from u to v in G that have no edges in common. Argue your algorithm's correctness and analyze its time complexity.
