问题描述 我们可爱的KK有一个有趣的数学游戏:这个游戏需要两个人,有N\left(1\leq N\leq 5*{10}^{4} \right)N(1≤N≤5∗10​4​​)个数,每次KK都会先拿数.每次可以拿任意多个数,直到NN个数被拿完.每次获得的得分为取的数中的最小值,KK和对手的策略都是尽可能使得自己的得分减去对手的得分更大.在这样的情况下,最终KK的得分减去对手的得分会是多少? 输入描述 第一行一个数T\left( 1\leq T\leq 10\right)T(1≤T≤10),表示数据组…

题目链接:Monkey and Banana 大意:给出n种箱子的长宽高.每种不限个数.可以堆叠.询问可以达到的最高高度是多少. 要求两个箱子堆叠的时候叠加的面.上面的面的两维长度都严格小于下面的. 简单的DP,依然有很多地发给当时没想到.比如优先级,比如这么简单粗暴的选择. /* 大意是.给出n种箱子的长宽高.每种不限个数.可以堆叠.询问可以达到的最高高度是多少. 要求两个箱子堆叠的时候叠加的面.上面的面的两维长度都严格小于下面的. 样例: 10 20 30 10 20 10 30 20 30…

常常做错的一道题.. 因为总是要有一个长度的 所以一开始的s与e都是1 maxx也是a[1] 然后再求 从i=2开始 在这里注意 me永远是当前i 而ms则可能留在原地 可能直接等于i 判断条件就是当前序列和与当前序列和加上a[i]的关系 好久没做题了..手生啊... #include<stdio.h> #include<string.h> #include<algorithm> #include<map> #include<math.h> us…
