CF1060C Maximum Subrectangle 题意翻译 现在给出一个长度为N的a数列,一个长度为M的b数列. 现在需要构造出一个矩阵c,其中ci,j=ai×bj.再给出一个x,请在矩阵中找出一个最大的矩形,使得这个矩形中的所有值的和小于等于x. 题目描述 You are given two arrays aa and bb of positive integers, with length n and m respectively. Let c be an n×m matrix…
题目链接:Codeforces 484B Maximum Value 题目大意:给定一个序列,找到连个数ai和aj,ai%aj尽量大,而且ai≥aj 解题思路:类似于素数筛选法的方式,每次枚举aj,然后枚举k,每次用二分找到小于k∗aj而且最大的ai,维护答案,过程中加了一些剪枝. #include <cstdio> #include <cstring> #include <algorithm> using namespace std; const int maxn =…
