Maximum Sum 大意:给你一个n*n的矩阵,求最大的子矩阵的和是多少. 思路:最開始我想的是预处理矩阵,遍历子矩阵的端点,发现复杂度是O(n^4).就不知道该怎么办了.问了一下,是压缩矩阵,转换成最大字段和的问题. 压缩行或者列都是能够的. int n, m, x, y, T, t; int Map[1010][1010]; int main() { while(~scanf("%d", &n)) { memset(Map, 0, sizeof(Map)); for(i…

题目大意:UVa 108 - Maximum Sum的加强版,求最大子矩阵和,不过矩阵是可以循环的,矩阵到结尾时可以循环到开头.开始听纠结的,想着难道要分情况讨论吗?!就去网上搜,看到可以通过补全进行处理,也是,通过补全一个相同的,问题就迎刃而解了,所以把n*n的矩阵扩展成2n*2n的矩阵就好了. #include <cstdio> #include <cstring> #define MAXN 160 int a[MAXN][MAXN], sum[MAXN][MAXN]; int…

Given an array of n elements.Find the maximum sum when the array elements will be arranged in such way. Multiply the elements of each pair and add to get maximum Sum. Sum could be larger so take mod with 10^9+7. Example1: Input: n= -,,,,-,-, Output:…
