WebA directed graph is strongly connected if and only if it has an ear decomposition, a partition of the edges into a sequence of directed paths and cycles such that the first subgraph in the sequence is a cycle, and each subsequent subgraph is either a cycle sharing one vertex with previous subgraphs, or a path sharing its two endpoints with ... WebFinal answer. 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 . dark phoenix 2019 dvd cover
