传送门 分析 这道题做了好长时间,题意就很难理解. 我们注意到这句话Vertices which have the i-th (1 ≤ i ≤ m) type of ice cream form a connected subgraph 也就是说在最后的图中相同颜色的点构成一个连通图 也就是说如果1和2.3在不同的点共同出现,那么2和3一定不会在某个点共同出现.于是我们可以直接暴力dfs,在每个点对没有颜色的冰激凌贪心染最小的颜色. 需要注意有某种冰激凌没有出现的情况. trick 代码 #in…
http://codeforces.com/contest/805/problem/E [题意] 染色数是很好确定,最少染色数是max(si)(最小为1,即使所有的si都为0,这样是单节点树形成的森林需要1种颜色),关键是确定染色方案. 一开始没看出来树有什么用,但其实一句话很关键:Vertices which have the i-th (1 ≤ i ≤ m) type of ice cream form a connected subgraph. 也就是说在原来的图中,含有相同的冰淇淋的点是…
