求解网络中的最短路径。假设某个计算机网络有n个站点，依次编号为1,2,…,n；有的站点之间有直接的线路连接（即这两个站点之间没有其它站点），有的站点之间没有直接的线路连接。如果用三元组（i,j,f）来表示该网络中的站点I和站点j之间有直接的线路连接且它们之间的距离为f 当已知该网络各站点之间的直接连接情况由m个三元组（i1,j1,f1）,(i2,j2,f2),…,(im,jm,fm)确定时，要求计算出对于网络中任意一个站点g(1≤g≤n)到其余各站点的最短距离。-the shortest path. Assuming a computer network n site, followed by No. 1, 2, ..., n; Some sites have direct connections (that is, between two sites are no other site), and some sites have no direct connections. If three yuan (i, j, f) to the network said the site j site and I have direct connections between them but the distance of f the network known as the site of the direct link between the situation by 3 m (i1, j1, f1), ( i2, j2, f2), ..., (im, jm, fm) to determine, calculate requirements for a network site arbitrary g (1 g n) of the rest of the site is the shortest distance.

关于计算机几种常见排序算法，在学习数据结构的时候曾自己动手写C语言的程序， 现发布出来与大家交流。虽然简单，但希望与大家在编程以及计算机算法方面能 够与大家交流，达到抛砖引玉的效果，恳切大家提出意见、建议。-On the computer several common sorting algorithms, data structures in the study had the time to write their own C language procedures, is published by the exchange with the U.S.. Although simple, but look forward to working with everyone in the programming and computer algorithms can exchange with the U.S. to initiate the effect, everyone sincerely offer comments, suggestions.
