题目链接:1199: Little Red Riding Hood 思路:dp(i)表示前i朵花能取得的最大价值,每一朵花有两种选择,摘与不摘,摘了第i朵花后第i-k到i+k的花全部枯萎,那么摘的话dp(i) = dp(i-k-1) + a[i],不摘就是dp(i) = dp(i-1),因此转移方程就是dp(i) = max(dp(i-k-1) + a[i], dp(i-1)). AC代码 #include <cstdio> #include <cmath> #include &l…

[题目]B. Robin Hood [题意]给定n个数字的序列和k次操作,每次将序列中最大的数-1,然后将序列中最小的数+1,求最终序列极差.n<=5*10^5,0<=k<=10^9,1<=ai<=10^9. [算法]模拟 [题解]关键在于,增加和减少可以分开操作. 将数列排序,从小到大增加前面若干个数到同一个数直到k次,再从大到小减少后面若干个数到同一个数直到k次,就可以得到结果. 也可以不排序直接二分”同一个数”找到恰好k次的位置. #include<cstdio&…

B. Robin Hood 讲道理:这种题我是绝对不去(敢)碰的.比赛时被这个题坑了一把,对于我这种不A不罢休的人来说就算看题解也要得到一个Accepted. 这题网上有很多题解,我自己是很难做出来的,于是参考了一下思路,确实很niub的一个题.先记录下来将来回来也有个参考. 题意:有n个人,每个人有一定数量的硬币a[i],每天将最富有的一个人的一枚硬币给最穷的那个人.求k天后最富有的人与最穷的人的差为多少. 思路:两遍二分啊,前所未见.因为k是固定的,我们先将所有人所能达到的上下界求出来,比如…
