CF-516B Drazil and Tiles

阅读更多关于 CF-516B Drazil and Tiles

题目链接： CF-516B Drazil and Tiles 题意给出$n\times m$的网格，有空白格子和被占据的格子，要把$1\times 2$的骨牌放进网格的空白格子中，骨牌不能重叠，问是否有放满空白格子的唯一解法，有则给出方案，否则输出"Not unique"。思路考虑拓扑排序，一个空白格子相邻四个方向的空白格子个数作为这个格子的度数，度数为1说明它只能往那个方向放骨牌，放完一个骨牌就更新其周边空白格子的度数，把度数为1的格子放进拓扑排序的队列，最终能放满整个网格的方案就是唯一解法。代码实现 #include <cstdio> #include <cstring> #include <queue> #define FOR(i, n) for (int i = 0; i < n; i++) const int N = 2010; char grid[N][N]; int deg[N][N]; int dir[][2] = {0, 1, 0, -1, 1, 0, -1, 0}; int n, m; bool check(int x, int y) { if (x >= 0 && y >= 0 && x < n && y < m && grid[x][y] == '.') return true; return false; } int main() { while

Redirect from one controller method to another controller method

阅读更多关于 Redirect from one controller method to another controller method

I am using Spring 3 and Tiles 2 in my application and have a bit of trouble with redirecting. Preferably, I would like to be able to just call or redirect from a Controller1 method to Controller2 method, but so far have been unsuccessful. I have tried to create a new entry in the pageviews.properties file. That way I could just return this name from Controller1 and it would look up my tiles def name from the xml files. createRejectionEmail.(parent)=tilesView createRejectionEmail.url=createRejectionEmail.page redirectRejectionEmail.(class)=org.springframework.web.servlet.view.RedirectView

How TO serve Map tiles from a database using Leafletjs

阅读更多关于 How TO serve Map tiles from a database using Leafletjs

问题 Leaflet js requires the following tile source format: http://localhost/tileserver/{z}/{x}/{y}.png How can I serve tile images from a database instead of file system using Leafletjs (and ASP.net) 回答1: You'll need to write a server application that reads a request URL, pulls tiles out of a database, and delivers them over the web. JavaScript does not read directly from databases. 回答2: This works very fast and seamlessly with Leaflet: Apparently Leaflet just uses the z,x,y place holders to

How do I have common error page templates with tiles in a Spring/MVC 3.0 app?

阅读更多关于 How do I have common error page templates with tiles in a Spring/MVC 3.0 app?

问题 I have a Spring MVC/3.0 app using tiles as it's view, this is working fine however I can't figure out how to get the error pages to also use tiles. I have in my web.xml <error-page> <error-code>404</error-code> <location>/WEB-INF/error/404.jsp</location> </error-page> which works fine as an ordinary view NOT using tiles, however when I change the location to one of the view names, the view is not found and renders the ordinary error page. My tiles.xml file for the view contains the following

Calculating tiles to display in a MapRect when “over-zoomed” beyond the overlay tile set

阅读更多关于 Calculating tiles to display in a MapRect when “over-zoomed” beyond the overlay tile set

I am working on an app that uses MKOverlay views to layer my own custom maps on top of the Google base map. I have been using Apple's excellent TileMap sample code (from WWDC 2010) as a guide. My problem - when "overzoomed" to a level of detail deeper than my generated tile set, the code displays nothing because there are no tiles available at the calculated Z level. The behavior I want - when "overzoomed" the app should just keep magnifying the deepest level of tiles. It is a good user experience for the overlay to become blurrier - it is a very bad experience to have the overlay vanish. Here

Accessing Spring beans from a Tiles view (JSP)

阅读更多关于 Accessing Spring beans from a Tiles view (JSP)

In Spring MVC I can access my beans in JSP using JstlView's exposedContextBeanNames (or exposeContextBeansAsAttributes). For example, then, in my JSP I can write (${properties.myProperty). But when the same JSP is a part of a tiles view, these properties aren't accessible. Is possible to configure Tiles properly or access these properties in another way? I'm using Spring MVC 3.0.2 and Tiles 2.2.1. Here's a bit of my configuration: <bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="order" value="1"/> <property name="viewClass" value=

Why would I use a templating engine? jsp include and jstl vs tiles, freemarker, velocity, sitemesh

阅读更多关于 Why would I use a templating engine? jsp include and jstl vs tiles, freemarker, velocity, sitemesh

问题 I'm about to choose to way to organize my view (with spring-mvc, but that shouldn't matter much) There are 6 options as far as I see (though they are not mutually exclusive): Tiles Sitemesh Freemarker Velocity <jsp:include> <%@ include file=".."> Tiles and Sitemesh can be grouped; so can Freemarker and Velocity . Which one within each group to use is not a matter of this discussion, there are enough questions and discussions about it. This is an interesting read, but can't quite convince me

JavaEE高级框架学习笔记（十）Struts布局——Tiles

阅读更多关于 JavaEE高级框架学习笔记（十）Struts布局——Tiles

0.前言 Java的学习前端和后端需要一起重视。前端页面的布局分布，用framset可以做到，但是如果把页面在细分为小块一些的内容，framset就不易办到。若是把页面视为行列交错的表格，每个表格内都可以填充内容，使用Struts的Tiles布局其实更为合适。假设要开发一个页面，如上图所示，当用户点击链接的时候，内容仅仅在右侧中间栏进行更改，以下有几种方案。 1.方案1 构造两个几乎完全一样的页面，仅在中间栏有所有不同。这样点击链接，看上去就显得没有变化，但是这种方法弊端很明显，比如说原本需要维护一份的代码，现在变成两份；网页再跳转的时候如果网速比较慢或者服务器相应比较慢的话，会造成使用的不流畅体验。。 2.方案2 将每个部分分为独立的页面，用JSP的include标签，把各部分内容包含在一个页面里面。以上述页面为例，可以拆分成左边（sidebar.jsp），右上（head.jsp），右下(foot.jsp），右中（content.jsp）拆开之后再用jsp的include把它们包含在一个页面里面。 index.jsp就是利用了jsp的include方法进行内容插入，有点像挖空——填空这样的过程。代码如下： <%@ page contentType="text/html; charset=UTF-8" %> <html> <head> <title
