Final answer. Transcribed image text: 22.1− 3 Given a weighted, directed graph G = (V,E) with no negative-weight cycles, let m be the maximum over all vertices v ∈ V of the minimum number of edges in a shortest path from the source s to v. (Here, the shortest path is by weight, not the number of edges.)

For example, all vertices of a graph can be selected by igraph_vs_all () and the graph independence means that igraph_vs_all () is not parametrized by a graph object.

Task: You are given a directed graph. Find out if the graph contains a negative cycle. Input: The first line contains a natural n(1 ≤ n ≤ 100) - the quantity of the graph's vertexes. The next n lines contain n numbers - the adjacency matrix of the graph. Every edge has weight less than 100000 .
