[POJ2482]Stars in Your Window 题面 vjudge 题解 第一眼还真没发现这题居然™是个扫描线 令点的坐标为\((x,y)\)权值为\(c\),则 若这个点能对结果有\(c\)的贡献,必须要矩形左下角的点的范围必须在\(([x,x+w),[y,y+h))\)之间 则按扫描线套路将一个类似矩形的范围拆成线\((x,y1,y2,c)\).\((x+w,y1,y2,-c)\)(依次表示横坐标.下端点纵坐标.上端点纵坐标.权值)即可 最后注意排序时不但要按\(x\)排,也要按…

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…

[转]mysql8.0 在window环境下的部署与配置 今天在阿里云window服务器上配置mysql环境,踩了一些坑,分享出来.需要的朋友可以看看.额,或许有人要吐槽我为什么不在linux上去配置,额,因为我window的那台服务器配置相对高些.本人技术方面偏向于.net,现在接触php项目所以搭建LAMP环境.只不过我的数据库放在window上的这台服务器. 言归正传 先选择版本,到mysql官方网站下载,你会发现各宗版本看得眼花缭乱的,不要惊慌先选择MySQL Community Edi…
