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…
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:…
