Given an undirected weighted graph with n nodes and m edges, find the shortest distance from the first node to the xth node (1-based index). Input / Output The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. In each test case, the first line contains 3 integers, n, m and q denoting the number of nodes in the graph, the nu
