杭电ACM1102——Constructing Roads

这题，简单的最小生成树的应用，只是输入的方式比较特殊。还会告诉你哪一些村庄是已经有路的。输入的第一个数n，是村庄的数目，然后下面n*n个数代表的是：第i行第j个就是村庄i和j之间的距离。理解了这个，就很容易写出代码了。使用并查集避免形成环。下面是AC的代码：#include#include#includeusingnamespacestd;classdata//两个村庄直接的数据，也就是距离{pu

这道题也是一道经典最小生成树的题目，用的prim算法。贵在会方法，并且能准确读懂题，我就读了好久，我犹豫的地方比方说：城镇B，C之间相连有一条路，如果城镇A可以通向C，那它也能通向B。开始我把它理解成了，A必须连着B，之间有条路；也必须连着C，之间有条路，其实不是这样。A通向B或C任何一个城镇就相当于也通向了另一个城镇。这才是最小生成树的意思吗，下面就好弄了。还有一个地方，就是正在建设的路，那不属

题意：村庄之间连通，要求输出最小权值和，注意有些村庄已经连通要点：Prim算法稍微变一下，因为是求权值和，已经连通的之间权值改为0即可，反正为0后面算的时候肯定是最小值，会加入集合的，然后权值又是0不影响。15347342Seasonal2421Accepted208K32MSC++826B2016-04-0314:36:19#include#include#includeintmap[105][

这道题目没有做出来，代码写好之后一直没有AC，本以为做了这么多最小生成树的题目，这道题一定没问题的，结果很遗憾，没有注意细节问题：首先，如何处理已经建好的路？已经建好的路说明这两个点是连通的，只要把他们间距设为0就好了。其次，注意循环的控制，我把第一个for中的i=1写成i=0了。Problem:1102(ConstructingRoads)JudgeStatus:AcceptedRunId:59
