• Help to solve "Robbery Problem"

  - by peiska

  Hello, Can anybody help me with this problem in C or Java? The problem is taken from here: http://acm.pku.edu.cn/JudgeOnline/problem?id=1104 Inspector Robstop is very angry. Last night, a bank has been robbed and the robber has not been caught. And this happened already for the third time this year, even though he did everything in his power to stop the robber: as quickly as possible, all roads leading out of the city were blocked, making it impossible for the robber to escape. Then, the inspector asked all the people in the city to watch out for the robber, but the only messages he got were of the form "We don't see him." But this time, he has had enough! Inspector Robstop decides to analyze how the robber could have escaped. To do that, he asks you to write a program which takes all the information the inspector could get about the robber in order to find out where the robber has been at which time. Coincidentally, the city in which the bank was robbed has a rectangular shape. The roads leaving the city are blocked for a certain period of time t, and during that time, several observations of the form "The robber isn't in the rectangle Ri at time ti" are reported. Assuming that the robber can move at most one unit per time step, your program must try to find the exact position of the robber at each time step. Input The input contains the description of several robberies. The first line of each description consists of three numbers W, H, t (1 <= W,H,t <= 100) where W is the width, H the height of the city and t is the time during which the city is locked. The next contains a single integer n (0 <= n <= 100), the number of messages the inspector received. The next n lines (one for each of the messages) consist of five integers ti, Li, Ti, Ri, Bi each. The integer ti is the time at which the observation has been made (1 <= ti <= t), and Li, Ti, Ri, Bi are the left, top, right and bottom respectively of the (rectangular) area which has been observed. (1 <= Li <= Ri <= W, 1 <= Ti <= Bi <= H; the point (1, 1) is the upper left hand corner, and (W, H) is the lower right hand corner of the city.) The messages mean that the robber was not in the given rectangle at time ti. The input is terminated by a test case starting with W = H = t = 0. This case should not be processed. Output For each robbery, first output the line "Robbery #k:", where k is the number of the robbery. Then, there are three possibilities: If it is impossible that the robber is still in the city considering the messages, output the line "The robber has escaped." In all other cases, assume that the robber really is in the city. Output one line of the form "Time step : The robber has been at x,y." for each time step, in which the exact location can be deduced. (x and y are the column resp. row of the robber in time step .) Output these lines ordered by time . If nothing can be deduced, output the line "Nothing known." and hope that the inspector will not get even more angry. Output a blank line after each processed case.

I am attempting to style the following element (taken from firefox web developer tools): html > body > div#wrapper > div#leftright > div.content > div.pageselect To my mind .pageselect should be the selector to do that, but I seem to be powerless to influence the style, and its just about sending me wacko! Why won't this work?

• Redis Cookbook Chat Recipe

  I am a new starter to Node.Js and Redis. I got the Redis cookbook and was trying out the Chat client & Server recipe.

• What's a clean way to have the server return a JavaScript function which would then be invoked?

  - by Khnle

  My application is architected as a host of plug-ins that have not yet been written. There's a long reason for this, but with each new year, the business logic will be different and we don't know what it will be like (Think of TurboTax if that helps). The plug-ins consist of both server and client components. The server components deals with business logic and persisting the data into database tables which will be created at a later time as well. The JavaScript manipulates the DOM for the browsers to render afterward. Each plugin lives in a separate assembly, so that they won't disturb the main application, i.e., we don't want to recompile the main application. Long story short, I am looking for a way to return JavaScript functions to the client from an Ajax get request, and execute these JavaScript functions (which are just returned). Invoking a function in Javascript is easy. The hard part is how to organize or structure so that I won't have to deal with maintenance problem. So concat using StringBuilder to end up with JavaScript code as a result of calling toString() from the string builder object is out of the question. I want to have no difference between writing JavaScript codes normally and writing Javascript codes for this dynamic purpose. An alternative is to manipulate the DOM on the server side, but I doubt that it would be as elegantly as using jQuery on the client side. I am open for a C# library that supports chainable calls like jQuery that also manipulates the DOM too. Do you have any idea or is it too much to ask or are you too confused? Edit1: The point is to avoid recompiling, hence the plug-ins architecture. In some other parts of the program, I already use the concept of dynamically loading Javascript files. That works fine. What I am looking here is somewhere in the middle of the program when an Ajax request is sent to the server. Edit 2: To illustrate my question: Normally, you would see the following code. An Ajax request is sent to the server, a JSON result is returned to the client which then uses jQuery to manipulate the DOM (creating tag and adding to the container in this case). $.ajax({ type: 'get', url: someUrl, data: {'': ''}, success: function(data) { var ul = $('<ul>').appendTo(container); var decoded = $.parseJSON(data); $.each(decoded, function(i, e) { var li = $('<li>').text(e.FIELD1 + ',' + e.FIELD2 + ',' + e.FIELD3); ul.append(li); }); } }); The above is extremely simple. But next year, what the server returns is totally different and how the data to be rendered would also be different. In a way, this is what I want: var container = $('#some-existing-element-on-the-page'); $.ajax({ type: 'get', url: someUrl, data: {'': ''}, success: function(data) { var decoded = $.parseJSON(data); var fx = decoded.fx; var data = decode.data; //fx is the dynamic function that create the DOM from the data and append to the existing container fx(container, data); } }); I don't need to know, at this time what data would be like, but in the future I will, and I can then write fx accordingly.

• Converting PHP pagination to jQuery?

  - by ClarkSKent

  Hey, I have been trying to get this pagination class that I am using to be more ajaxy - meaning when I click on the page number like page [2] the data loads, but I want to load in the data without going to a different page (HTTP request in the background, with no page reloads). Being new to both php and jquery, I am a little unsure on how to achieve this result, especially while using a php class. This is what the main page looks like by the way: <?php $categoryId=$_GET['category']; echo $categoryId; ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_page.js"></script> <?php //Include the PS_Pagination class include('ps_pagination.php'); //Connect to mysql db $conn = mysql_connect('localhost', 'root', 'root'); mysql_select_db('ajax_demo',$conn); $sql = "select * from explore where category='$categoryId'"; //Create a PS_Pagination object $pager = new PS_Pagination($conn, $sql, 3, 11, 'param1=value1&param2=value2'); //The paginate() function returns a mysql //result set for the current page $rs = $pager->paginate(); //Loop through the result set echo "<table width='800px'>"; while($row = mysql_fetch_assoc($rs)) { echo "<tr>"; echo"<td>"; echo $row['id']; echo"</td>"; echo"<td>"; echo $row['site_description']; echo"</td>"; echo"<td>"; echo $row['site_price']; echo"</td>"; echo "</tr>"; } echo "</table>"; echo "<ul id='pagination'>"; echo "<li>"; //Display the navigation echo $pager->renderFullNav(); echo "</li>"; echo "</ul>"; ?> <div id="loading" ></div> <div id="content" ></div> Would I need to do something with this part of the class?, as seen above: $pager = new PS_Pagination($conn, $sql, 3, 11, 'param1=value1&param2=value2'); Or this?: echo $pager->renderFullNav(); I don't no much about jquery,but i guess I would start it like: $("#pagination li").click(function() { Then load something maybe... I don't no. Any help on this would be great. Thanks.

• show hidden div tag from another page

  - by neueweblernen

  I'm trying to link to an all-inclusive FAQ page from various pages. The answers are contained in tags, nested within a line item of an unordered list housed by categories. The FAQ page has the following categories: Practical Nurse Exam Online Renewal Practice Hours etc. Under Practical Nurse Exam, there are sub categories, subjects, with questions below in tags that expand onClick. (e.g. Examination Day, Exam Results, etc.) Let's say I'm on a different page called Registration and there's a link to the FAQs for Exam Results. I'm able to link to the page and included the hashtag on the anchor or Exam Results, but it does not expand the subcategory. I've read this thread but it didn't work for me. Please help! The code is below: <script type="text/javascript"> function toggle(Info,pic) { var CState = document.getElementById(Info); CState.style.display = (CState.style.display != 'block') ?
