Shortest cycle in graph
SpletShortest Path Visiting All Nodes Hard 3.1K 138 Companies You have an undirected, connected graph of n nodes labeled from 0 to n - 1. You are given an array graph where graph [i] is a list of all the nodes connected with node i by an edge. Return the length of the shortest path that visits every node. SpletIn the first example, the shortest cycle is (9, 3, 6, 28) (9,3,6,28) . In the second example, the shortest cycle is (5, 12, 9) (5,12,9) . The graph has no cycles in the third example.

SpletIf you store parents, this will give you a shortest-path tree rooted at u. Preprocess the tree for LCA queries. Consider some edge e = {v, x} that is not in the shortest-path tree. If lca(v, x) = u, then the path is a simple cycle containing u, with weight dv + dx + w(e). The answer for vertex u is the minimum weight over all such cycles. Code. SpletThe key idea is that a shortest cycle is comprised of a shortest path between two vertices, say v and w, that does not include edge v-w, plus the edge v-w. We can find the shortest …
