$n<=1000,m<=1000$,$n*m$的01矩阵,给$t<=1000000$个询问,每次问一个矩形中最大的1正方形的边长. 先想想不考虑“一个矩形中”的限制,那记$f(i,j)$--以$(i,j)$为右下角的最大的正方形,那 很好,那现在加入一个边界限制,由于边长r的正方形同时也是边长r-1,r-2……的,那来二分答案吧,现在对二分的答案$x$就检查一个区域里的$f$数组中最大的那一个是否大于等于$x$.查静态区间最大,用ST表啦!拓展到二维情况即可. #include<s…

题目链接 Animals and Puzzle 题意  给出一个1e3 * 1e3的01矩阵,给出t个询问,每个询问形如x1,y1,x2,y2 你需要回答在以$(x1, y1)$为左上角,$(x1, y2)$为右下角的子矩阵中,最大的全1正方形的边长. 首先考虑DP预处理. $f[i][j]$表示以$f[i][j]$为右下角的最大的全1正方形的边长. 则$f[i][j] = min(f[i - 1][j], f[i][j - 1], f[i - 1][j - 1]) + 1$ 我们对$f[i][…

题目链接 给一个01矩阵, 然后每个询问给出两个坐标(x1, y1), (x2, y2). 问你这个范围内的最大全1正方形的边长是多少. 我们dp算出以i, j为右下角的正方形边长最大值. 然后用二维st表预处理出所有的最大值. 对于每个询问, 我们二分一个值mid, 查询(x1 + mid -1, y1 + mid -1), (x2, y2)这个范围内的最大值是否大于mid .如果大于的话就说明在(x1, y1), (x2, y2)范围内存在一个边长为mid的正方形. #include <bi…

Puzzle 面向服务/切面AOP开发框架 For .Net AOP主要实现的目的是针对业务处理过程中的切面进行提取,它所面对的是处理过程中的某个步骤或阶段,以获得逻辑过程中各部分之间低耦合性的隔离效果. 日常的产品开发中最常见的就是数据保存的功能.举例来说,现在有个用户信息数据保存的功能,我们希望在数据保存前对数据进行校验,其中现在能想到的校验就包含数据完整性校验和相同数据是否存在校验.按照传统的OOP(面向对象程序设计),我们需要定义一个IUserDataSaveService(用户数据保存…
