题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4052 初始给你w*h的矩阵,给你n个矩形(互不相交),按这些矩形尺寸把初始的矩形扣掉,形成一个新的'矩形'.然后给你1*m大小的矩形,问这个矩形在新'矩形'中有多少种放法. 一开始没想法==,然后看了看题解,说是线段树做的. 要是m为1的话,那答案就是剩下的面积了. 不为1的话,可以把n个矩形的面积扩展一下(我是向右扩展),比如x1 y1 x2 y2 的矩形扣掉,就相当于x1  y1  x2+m-1…

Abstract We present the internals of QEMU, a fast machine emulator using an original portable dynamic translator. It emulates several CPUs (x86, PowerPC, ARM and Sparc) on several hosts (x86, PowerPC, ARM, Sparc, Alpha and MIPS). QEMU supports full s…

今日这场比赛我们准备的题比较全面,二分+数论+最短路+计算几何+dp+思维+签到题等.有较难的防AK题,也有简单的签到题.为大家准备了一份题解和AC代码. A - Meeting with Aliens UVA - 10570 题目意思:让一个成环的序列变成有序的,正序逆序都可以,问最小交换次数. 解题思路:对于一个长度为n的元素互异的序列,通过交换实现有序的最小的交换次数是=n - 被分解成单循环的个数.数据比较小,正着来一遍,反着来一遍,取最小就可以了. #include<iostream>…
