True or False: Prim's algorithm will produce a graph with equal number of vertices and edgesRun BFS algorithm on the following graph starting with vertex s. Whenever there is a choice of vertices, choose the one that is alphabetically first. What is the order that the vertices are visited? What is the shortest path from vertex s to vertex b?Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You are given a coordinated chart of n vertices and m edges. Vertices are numbered from 1 to n. There is a token in vertex 1. The accompanying activities are permitted: Token development. To move the token from vertex u to vertex v in case there is an edge u→v in the chart. This activity requires 1 second. Chart interpretation. To render every one of the edges in the diagram: supplant each edge u→v by an edge v→u. This activity requires some investment: k-th rendering requires 2k−1 seconds, for example the primary rendering requires 1 second, the subsequent one requires 2 seconds, the third one requires 4 seconds, etc. The objective is to move the token from vertex 1 to vertex n in the most limited conceivable time. Print this time modulo 998244353. Input The primary line of input contains two integers n,m (1≤n,m≤200000). The following m lines contain two integers…

Computer science. society can be addressed by an associated, undirected chart of n vertices and m edges. The vertices address individuals, and an edge (i,j) addresses a companionship between individuals I and j. In the public eye, the I-th individual has a pay artificial intelligence. An individual I is desirous of individual j if aj=ai+1. That is if individual j has precisely 1 more unit of pay than individual I. The general public is called entrepreneur if for each pair of companions one is desirous of the other. For certain fellowships, you know which companion is jealous of the other. For the leftover fellowships, you don't have the foggiest idea about the bearing of jealousy. The pay imbalance of society is characterized as max1≤i≤nai−min1≤i≤nai.
