Then G cannot also contain a path all its outgoing edges. If it is a 0, it means that the vertex corresponding to index j cannot be a sink. We now check for whether row i has only 0s and whether row j as only 1s except for A[i][i], which will be 0. Am un grafic cu n noduri ca matricea de adiacență.. Este posibil să detectați o chiuvetă în mai puțin de O(n) timp?. x 27 in. What I called "a link from i to j" is a directed edge starting at i and ending at j. graph G = (V,E). In a directed graph, G represented as E (u,v), where u->v is an edge in the graph. This article is attributed to GeeksforGeeks.org. If so then node 1 is a universal sink otherwise the graph has no universal sink. Negative weight cycles cause the problem to be ill-defined. This program eliminates non-sink vertices in O(n) complexity and checks for the sink property in O(n) complexity.
