最开始使用递归DP解,stack overflow.化简了一些,复杂度为O(n)就过了. #include <stdio.h> int main() { int case_n, n; int i, j, tmp; int beg, end, sum, max_sum; int number; scanf("%d", &case_n); ; i<=case_n; i++) { scanf("%d", &n); beg = ; tmp…
题目描述: Given a non-empty 2D matrix matrix and an integer k, find the max sum of a rectangle in the matrix such that its sum is no larger than k. 解题思路: 根据题意,寻找二维数组中所有可以组成的矩形中面积不超过k的最大值,所以必须要求出可能组成的矩形的面积并与k比较求出最终结果.这里为了最终不超时,可以在一下方面进行优化: 1.设置一个数组比较当前列(或…
