( 1076 ) E Shortest Paths PROGRAMMING *special shortest paths

You are given a graph of (n) nodes and (m) undirected edges. Find the shortest path from node (1) to each node with Dikjstra's algorithm. The first line contains two integers (n) and (m) ((2 \leq n \leq 100, 0 \leq m \leq \frac{n(n-1)}{2})). The following (m) lines contain (3) integers each: (u), (v), and (w), denoting an undirected edge from (u) to (v) with weight (w) ((1 \leq u, v \leq n, 0 \leq w \leq 10^5)). Output the shortest path from node (1) to each node (2, \dots, n). If a node is not reachable from node (1), output (-1).
