OpenJudge - 07:Shortest Path

描述

There is a graph with N nodes. Given the length of each edge between the nodes. Find the shortest path from S to E.

输入

First line: three positive integer number N (N <= 100), S (S <= N), E(E <= N).
Next N lines: the i-th line contains N non-negative integers (<= 100), indicating the length of edge from the i-th node to any nodes.

输出

One line contains several integers, indicating the indexes of node in the shortest path from S to E.

翻译：

有一个带有N个节点的图。给出每个节点之间的边的长度，找到从S到E的最短路径。

输入：

第一行：三个正整数N,S,E。

接下来的N行：第i行有N个非负整数，表明从第i个节点到任意节点的距离。

输出：

一行包括几个整数，表明从S到E的最短节点路径。
