 题意: Alice和Bob有n个长方形,有长度和宽度,一个矩形能够覆盖还有一个矩形的条件的是,本身长度大于等于还有一个矩形,且宽度大于等于还有一个矩形.矩形不可旋转.问你Alice最多能覆盖Bob的几个矩形? 思路:贪心,先依照h将Alice和Bob的矩形排序,对于Alice的每一个矩形.假设Bob的矩形的h小于Alice的h,将Bob的w插入到集合中. 然后,在集合中找到不大于Alice矩形d的最大的Bob的d,那么这样做肯定是最优的. #include<cstdio> #includ…

copy VS study 1.每堆部是1的时候,是3的倍数时输否则赢: 2.只有一堆2其他全是1的时候,1的堆数是3的倍数时输否则赢: 3.其他情况下,计算出总和+堆数-1,若为偶数,且1的堆数是偶数,则一定输: 4.不在上述情况下则赢. #include<stdio.h> int main() { ; int _case,i,n,x; int flag1,flag2,flag,sum; scanf("%d",&_case); while(_case--) { j…

题意: 一个无限大的棋盘,一开始在1,1,有三种移动方式,(x+1,y)(x,y+1) (x+k,y+k)最后走到nm不能走了的人算输.. 析:.我们看成一开始在(n,m),往1,1,走,所以自然可以从1,1,开始递推往出,那么打表程序就出来了.. 打出表以后我们观察到k等于1时稍有特殊,其他则与  (min(cx,cy)&1)^((n+m)&1)) 有关ps(其中cx=n/(k+1),cy=m/(k+1)) 那么就愉快的分类讨论外加试一试和表对照一下就好了.. 代码如下: #includ…
