题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1024 题目大意:有多组输入,每组一行整数,开头两个数字m,n,接着有n个数字.要求在这n个数字上,m块数字的最大和.比如2 6 -1 4 -2 3 -2 3,就是(4 -2 3)和(3)这两块最大和为8. 解题思路:当成有m层,我们可以设置两个数组dp,mpre.dp[j]记录当前这一层包含a[j]时的最大值(包含a[j]),mpre[j]个记录上一层到第j-1个位置时的最大和(不一定包含a[j])…

题目链接 http://acm.hdu.edu.cn/showproblem.php?pid=1024 题意:给定一个数组,求其分成m个不相交子段和的最大值. 这题有点问题其实m挺小的但题目并没有给出. dp[i][j]表示取第i 位的数共取了j段然后转移方程显然为 dp[i][j]=max(dp[i - 1][j]+a[j] , max(dp[j - 1][j - 1]~dp[i - 1][j - 1]))(大致意思是取第i位要么i-1位取了j个那么a[j]刚好能与i-1拼成一段,或者j -…
