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。
