题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1024 题意就是有n个数分成m段,求最大的和: dp[i][j]表示把 j 个数分成 i 段,选择第 j 个数的结果,而并不是当前的最优解, 那么要考虑的是第i个数的数是自己成一段还是和前面的成一段 所以dp[i][j]=max(dp[i][j-1]+a[j], Max+a[j]); 其中Max为前 j-1 个数字分成 i-1 段中的最大值: 由于题中n为100w,m不知道是多少,所以开二维数组可能不…

题目来源:http://acm.hdu.edu.cn/showproblem.php?pid=1024 (http://www.fjutacm.com/Problem.jsp?pid=1375) 题意:长度为n的序列里,m段不相关区间的最大和 思路:我们先要确定一个东西,就是状态,这里我用dp[i][j]表示前j个数在取a[j]情况下分i段的最大和: 那么我们为了找规律,可以先来一发Excel,就以样例为例子: 然后我们可以发现其实红圈里的8是状态dp[2][6](i=2, j=6),那么我们可…
