从文件读入一个有向正权图(n 个结点,m 条边)的权矩阵表示,输出这个图中某一结点到 其余各结点的最短路径长度。

程序必须使用 Dijkstra 算法,使用其他算法(比如穷举)不符合要求。-Reading from a file into a right to a positive figure (n nodes, m edges) of the weight matrix, said output this figure a junction to the length of the shortest path to the rest of the nodes. Must use Dijkstra algorithm, using other algorithms (such as exhaustive) does not meet the requirements.
