CF1914F Programming Competition 贪心原则的DP?

终于理解了... 希望写给小伙伴们,希望大伙可以理解。 先确定贪心规则,即当最大子树不超过根子树减一的一半时,内部节点可以完全匹配。否则,可以先拿其他子树节点与最大子树内部节点匹配,子树内部再进行匹配。啥你说子树内部不够匹配怎么办?可以这么想,你这样都到匹配上限了,已经完全可以达到最优秀情况,取ma ......

CF768G The Winds of Winter题解

我们考虑暴力咋做,每次得到一个森林之后,必定是从最大的树上摘一棵子树,挪到最小的树上,所以此时的答案为 \(max(siz_{mx}-x,siz_{mn}+x,siz_{次大值} )\),于是发现 \(x=\frac{siz_{mx}-siz_{mn}}{2}\) 时答案最优,所以只需找到这个值的前 ......
