这个错误就是作为Region的view添加时选成了界面,正确的应在添加时选择用户控件. 解决方法: 这俩处的Window改为UserControl即可.…

POJ 2482 Stars in Your Window 题目链接 题意:给定一些星星,每一个星星都有一个亮度.如今要用w * h的矩形去框星星,问最大能框的亮度是多少 思路:转化为扫描线的问题,每一个星星转化为一个矩形,那么等于求矩形相交区域值最大的区域,利用线段树去维护就可以 代码: #include <cstdio> #include <cstring> #include <algorithm> using namespace std; typedef long…

题意:在二维坐标系中有一些带权值的点,要求用一个长宽指定不能互换的框套住其中的一些,使得它们的权值和最大. n<=10000 x,y<=2^31 思路:首先按X排序,将Y坐标离散化,X坐标用扫描线框定,每个点(x,y)在x中只对y有a[i]的贡献,y+h有-a[i]的贡献,线段树(树状数组更好写)维护最大子段和即可. ..]of record l,r,s,m:int64; end; x,y,c,a,h:..]of int64; n,m,i,j,tt,ww,up,w1,h1:longint; a…

题目不说了,可以用线段树或者单调队列,下面附上代码. 线段树: #include <iostream> #include <stdio.h> #include <algorithm> /* AC 线段树每个节点存储对应区间的最大值.最小值,然后直接查询即可.6594MS. */ using namespace std; ; const int INF=0x3f3f3f3f; int minans[maxn],maxans[maxn]; int small,bigger;…

原理文档没有跟我开玩笑呢? 建议放在盘符根目录下 ,无视的我,检查了多遍jdk环境,检查了多遍bat文件内容,仍然没有解决 找不到或无法加载主类 直到我乖乖的把目录放跟盘符才解决,心好累= =! 可能是文件路径过深造成的,具体原因还要看源码,慢慢来…
