给一个数列,问最少修改多少个元素使数列严格递增.如果不是要求“严格”递增,那就是求最长不降子序列LIS,然后n-LIS就是答案.要严格递增也好办,输入的时候用每个数减去其下标处理一下就行了. /* * Author : ben */ #include <cstdio> #include <cstdlib> #include <cstring> #include <cmath> #include <ctime> #include <iostr…

题目链接: http://acm.hdu.edu.cn/showproblem.php?pid=5125 题解: 这个题dp[i][0],dp[i][1]数组分别记录在第i个位置取a[i]和b[i]时可以取到最长上升子序列的长度,然后开一个m[i][0]和m[i][1]分别表示取到第i个位置时最少的交换次数.然后进行4次比较,最后取最大值的时候非常巧妙,如果m[i][0]>M,那么证明这个序列里面多了 m[i][0]-M 个数,所以要减掉这么多个数. 蒟蒻感觉别人好强啊.... #include…

HDU 1087 题目大意:给定一个序列,只能走比当前位置大的位置,不可回头,求能得到的和的最大值.(其实就是求最大上升(可不连续)子序列和) 解题思路:可以定义状态dp[i]表示以a[i]为结尾的上升子序列的和的最大值,那么便可以得到状态转移方程 dp[i] = max(dp[i], dp[j]+a[i]), 其中a[j]<a[i]且j<i; 另外每个dp[i]可以先初始化为a[i] 理解:以a[i]为结尾的上升子序列可以由前面比a[i]小的某个序列加上a[i]来取得,故此有dp[j]+a[…
