1786. Number of Restricted Paths From First to Last Node There is an undirected weighted connected graph. You are given a positive integer n which denotes that the graph has n nodes labeled from 1 to n, and an array edges where each edges[i] = [ui, vi, weighti] denotes that there is an edge between nodes ui and vi with weight equal to weighti. A path from node start to node end is a sequence of nodes [z0, z1, z2, …, zk] such that z0 = start and zk = end and there is an edge between zi and zi+1 ...
