题意: 输入两个正整数N和M(存疑M是否为整数,N<=1000,M<=500)表示月饼的种数和市场对于月饼的最大需求,接着输入N个正整数表示某种月饼的库存,再输入N个正数表示某种月饼库存全部出手的利润.输出最大利润. trick: 测试点2可能包含M不为整数的数据.(尽管题面说明M是正整数,可是根据从前PAT甲级题目的经验,有可能不是整数.....) AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.…

题意:输入一个正整数N(实则<=1e5),接着输入一行N个正整数(<=1e4).降序输出螺旋矩阵. trick: 测试点1,3运行超时原因:直接用sqrt(N)来表示矩阵的宽会在N是素数时出错,直接扫一遍找一个最大因子即可,简单粗暴. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ]; ][]; int main(){ ios::sync_wi…
