Description: Floyd-Warshall算法描述
1)适用范围：
a)APSP(All Pairs Shortest Paths)
b)稠密图效果最佳
c)边权可正可负
2)算法描述：
a)初始化：dis[u,v]=w[u,v]
b)For k:=1 to n
For i:=1 to n
For j:=1 to n
If dis[i,j]>dis[i,k]+dis[k,j] Then
Dis[I,j]:=dis[I,k]+dis[k,j]
c)算法结束：dis即为所有点对的最短路径矩阵
3)算法小结：此算法简单有效，由于三重循环结构紧凑，对于稠密图，效率要高于执行|V|次Dijkstra算法。时间复杂度O(n^3)。
考虑下列变形：如(I,j)∈E则dis[I,j]初始为1,else初始为0，这样的Floyd算法最后的最短路径矩阵即成为一个判断I,j是否有通路的矩阵。更简单的，我们可以把dis设成boolean类型，则每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”来代替算法描述中的蓝色部分，可以更直观地得到I,j的连通情况。

Description: 用C语言实现最短路径算法中的Floyd-Warshall算法，这个算法可以用来解决信号处理中的一些问题。floyd_warshall.c是源程序；distance_2.txt文件存放图中各点之间的距离，以99999表示无穷大；floyd.txt文件是输出文件，其中存放各轮得到的输出矩阵，以及最后得到的各点间最短距离，如果有负回路则返回FALSE。-C language shortest path algorithm of Floyd-Warshall algorithm, The algorithm can be used to solve signal processing some of the problems. Floyd_warshall.c yes source; distance_2.txt document storage map of the distance between points, 99,999 said to infinity; floyd.txt document output files, which kept the round of the output matrix, and finally come to the point of the shortest distance, If there is a negative loop it returns FALSE.

Description: 用最短路径算法算出特定两点之间的距离
输入：直接读取net.in文件
第一行为四个整数N,M,S,T,每两个整数之间用一个空格隔开，分别表示网络的节点（编号为1到N），网络线段数，以及起点终点编号
接下来M行，每行三个整数U,V,D，每个整数之间用空格隔开，表示节点U和V之间有一条线路相连，距离是D，（两个节点可能有多条线路）
输出：直接写入到net.out文件，输出只有一行，表示从S点到T点的最短距离（如果不通则输出-1） （N<=100，M<=N*N,D<=1000）(Use the shortest path algorithm to calculate the distance between two specific two points
Input: read the net.in file directly
The first behavior is four integers N, M, S and T. Every two integers are separated by a space, representing the node of the network (number 1 to N), the number of network segments, and the origin and destination number.
Next, M row, each row three integers U, V, D, each integer is separated by spaces, indicating that there is a line between nodes U and V, the distance is D, (there may be multiple lines in two nodes).
Output: write directly to net.out file, output only one line, which indicates the shortest distance from S point to T point (if it doesn't connect, output -1) (N<=100, M<=N*N, D<=1000).
