Single Source Shortest Path
For a given weighted graph G=(V,E), find the shortest path from a source to each vertex. For each vertex u, print the total weight of edges on the shortest path from vertex 0 to u.
In the first line, an integer n denoting the number of vertices in G is given. In the following n lines, adjacency lists for each vertex u are respectively given in the following format:
u k v1 c1 v2 c2 ... vk ck
Vertices in G are named with IDs 0,1,...,n−1. u is ID of the target vertex and k denotes its degree. vi(i=1,2,...k) denote IDs of vertices adjacent to u and ci denotes the weight of a directed edge connecting u and vi (from u to vi).
