  • Still failing a function, not sure why...ideas on test cases to run?

    - by igor
    I've been trying to get this Sudoku game working, and I am still failing some of the individual functions. All together the game works, but when I run it through an "autograder", some test cases fail.. Currently I am stuck on the following function, placeValue, failing. I do have the output that I get vs. what the correct one should be, but am confused..what is something going on? EDIT: I do not know what input/calls they make to the function. What happens is that "invalid row" is outputted after every placeValue call, and I can't trace why.. Here is the output (mine + correct one) if it's at all helpful: http://pastebin.com/Wd3P3nDA Here is placeValue, and following is getCoords that placeValue calls.. void placeValue(Square board[BOARD_SIZE][BOARD_SIZE]) { int x,y,value; if(getCoords(x,y)) { cin>>value; if(board[x][y].permanent) { cout<< endl << "That location cannot be changed"; } else if(!(value>=1 && value<=9)) { cout << "Invalid number"<< endl; clearInput(); } else if(validMove(board, x, y, value)) { board[x][y].number=value; } } } bool getCoords(int & x, int & y) { char row; y=0; cin>>row>>y; x = static_cast<int>(toupper(row)); if (isalpha(row) && (x >= 'A' && x <= 'I') && y >= 1 && y <= 9) { x = x - 'A'; // converts x from a letter to corresponding index in matrix y = y - 1; // converts y to corresponding index in matrix return (true); } else if (!(x >= 'A' && x <= 'I')) { cout<<"Invalid row"<<endl; clearInput(); return false; } else { cout<<"Invalid column"<<endl; clearInput(); return false; } }

  • Express highest floating point quantity that is less than 1

    - by edA-qa mort-ora-y
    I was doing some rounding calculations and happened upon a question. How can I express the highest quantity less than 1 for a given floating point type? That is, how I write/represent value x such that x < 1, x + y >= 1 for any y > 0. In fractions this would be x = (q-1)/q where q is the precision of the type. For example, if you are counting in 1/999 increments then x = 998/999. For a given type (float, double, long double), how could one express the value x in code? I also wonder if such a value actually exists for all values of y. That is, as y's exponent gets smaller perhaps the relation doesn't hold anymore. So an answer with some range restriction on y is also acceptable. (The value of x I want still does exist, the relationship may just not properly express it.)

  • Carscading dropdowns

    - by SnowJim
    Hi! I am working with carscading dropdowns in MVC. It apears that I will not be able to easaly create dropdowns on demand, instead I will have to add the dropdowns before sending it to the client. This is how are doing it right now : In the aspx page <%: Html.DropDownListFor(model => model.ModelViewAd.Category1, Model.ModelViewAd.Category1List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category2, Model.ModelViewAd.Category2List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category3, Model.ModelViewAd.Category3List, "-- Välj kategori --")%> <%: Html.DropDownListFor(model => model.ModelViewAd.Category4, Model.ModelViewAd.Category4List, "-- Välj kategori --")%> This is rendered like this : <select id="ModelViewAd_Category1" name="ModelViewAd.Category1"> <option value="">-- V&#228;lj kategori --</option> <option value="10">Fordon</option> <option value="15">F&#246;r hemmet</option> <option value="17">Bostad</option> </select> <select id="ModelViewAd_Category2" name="ModelViewAd.Category2"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category3" name="ModelViewAd.Category3"> <option value="">-- V&#228;lj kategori --</option> </select> <select id="ModelViewAd_Category4" name="ModelViewAd.Category4"> <option value="">-- V&#228;lj kategori --</option> </select> This is how the script on the page looks like : <script type="text/javascript"> $(function () { $("select#ModelViewAd_Category1").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category2").addItems(data.d); }); }); $("select#ModelViewAd_Category2").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category3").addItems(data.d); }); }); $("select#ModelViewAd_Category3").change(function () { var id = $(this).val(); var urlAction = "/AdCategory/GetCategoriesByParent1/" + id; $.getJSON(urlAction, { id: id }, function (data) { $("#ModelViewAd_Category4").addItems(data.d); }); }); }); </script> And then I have a included file that contains this : $.fn.clearSelect = function () { return this.each(function () { if (this.tagName == 'SELECT') this.options.length = 0; }); } $.fn.addItems = function (data) { return this.clearSelect().each(function () { if (this.tagName == 'SELECT') { var dropdownList = this; $.each(data, function (index, optionData) { var option = new Option(optionData.Text, optionData.Value); if ($.browser.msie) { dropdownList.add(option); } else { dropdownList.add(option, null); } if ($(this).children().size() < 2) { $(this).hide(); } else { $(this).show(); } }); } }); } The problem I now have is that I need to hide the dropdowns that do not contain any options or do only contains one option. This should be checked when doing a call to the service as well as when the page is sent to the client ("POSTBACK"). What I need is : 4 Dropdowns Only the first dropdown is visible when first entering the page. When selecting a option from dropdown1 the dropdown2 will be populated and so on If there is only 1 option then the dropdown should be hidden If all 4 dropdowns is set and the end-user change dropdown 1, then dropdown2 should be reloaded and the rest be hidden If the user have selected some of the dropdowns(say 1,2 and 3) and hit submit and the page is not accepted on the server side(not valid) the dropdowns should be set exacly as when the user cliked the submit button when the page returns to the user. Any suggestions on this?

  • ASP.NET MVC URL Routing problem

    - by Sadegh
    hi, i have defined a route as below: context.MapRoute("SearchEngineWebSearch", "search/web/{query}/{index}/{size}", new { controller = "search", action = "web", query = "", index = 0, size = 5 }); and action method to handle request match with that: public System.Web.Mvc.ActionResult Web(string query = "", int index = 0, int size = 5) { if (string.IsNullOrEmpty(query)) return RedirectToRoute("SearchEngineBasicSearch"); var search = new Search(); var results = search.PerformSearch(query, index, size); ViewData["Query"] = query; if (results != null && results.Count() > 0) { ViewData["Results"]= results; return View("Web"); } else return View("Not-Found"); } and form to sent parameter to action method: <% using (Html.BeginForm("Web", "Search", FormMethod.Post)) { %> <input name="query" type="text" value="<%: ViewData["Query"]%>" class="search-field" /> <input type="submit" value="Search" class="search-button" /> <input type="hidden" name="index" value="2" /> <input type="hidden" name="size" value="2" /> <%} %> now after click on submit and sending value to action method all route values updated but url values still is equals to first time of sending parameter. for example if i sent for first time request such as http://localhost/search/web/google and for next time http://localhost/search/web/yahoo, query parameter which passed to action method is yahoo but url after postback is http://localhost/search/web/google still! can anybody help me plz? ;)

  • How to highlight text automatically inside an UIAlertView text field

    - by user333624
    Hello everyone I have an UIAlertView with a textfield that shows a default value and two buttons, one to cancel and the other one to confirm. What I am trying to do is that when the alert view is popped up the default value is highlighted so the user can override the whole value faster than manually erasing it. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Title" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Continue",nil]; [alerta addTextFieldWithValue:@"87893" label:@"value"]; UITextField *textField = [alert textField]; campoTexto.highlighted = YES; campoTexto.keyboardType = UIKeyboardTypeNumbersAndPunctuation; [alertt show]; [alert release]; } for some reason there is a highlighted attribute for the textfield but it doesn't seem to work and there is no trail of that attribute in the Class documentation.

  • J2EE: Default values for custom tag attributes

    - by Nick
    So according to Sun's J2EE documentation (http://docs.sun.com/app/docs/doc/819-3669/bnani?l=en&a=view), "If a tag attribute is not required, a tag handler should provide a default value." My question is how in the hell do I define a default value as per the documentation's description. Here's the code: <%@ attribute name="visible" required="false" type="java.lang.Boolean" %> <c:if test="${visible}"> My Tag Contents Here </c:if> Obviously, this tag won't compile because it's lacking the tag directive and the core library import. My point is that I want the "visible" property to default to TRUE. The "tag attribute is not required," so the "tag handler should provide a default value." I want to provide a default value, so what am I missing? Any help is greatly appreciated.

  • Use date operations on a computed field filter in a view

    - by stephenhay
    I'd like to expose a filter in Views based on a Computed Field. This field should utilize the date operation "less than". Apparently, a date type is not available to computed field (varchar is). However, using varchar results in views treating the field as a string rather than as a date, without the operation I'm looking for. So I tried using a timestamp instead of a date, which allowed me to use an integer data type. The exposed view gives me a "less than" operation, but as it's still not a date, the user must type in a timestamp. Not handy. So I'm thinking the best way to do this is to create a new (hidden) CCK field which is a date field, and set the value of this field to the value of the Computed Field. I can then use the new CCK field for my exposed filter. But I'm not getting anywhere with this, as I'm unsure how to set another CCK field with a Computed Field. To return the value to the computed field itself, I'm using the standard: $node_field[0]['value'] = $newestdate; I would like to set the value of the new CCK field to $newestdate as well. Can anyone help?

  • How to pass values from client side to server side ?

    - by manojp1988
    Hi All, I got a situation to transfer values from jsp to servlet's action class. Previously we did it using <input type="hidden" id="name" value="manoj" /> we take this value in action class by request.getParameter("name"). But now we couldn't pass value like "Hi\n i am\n Manoj". Since it has new line included in the string we couldn't take it like this to action. So how I can take value like this to action or is there any way other than hidden input? Thanks .

  • setting cookies

The following method doesn't work: def set_cookie(opts={}) args = { :name => nil, :value => nil, :expires => Time.now+314, :path => '/', :domain => Cambium.uri #contains the IP address of the dev server this is running on }.merge(opts) raise ArgumentError, ":name and :value are mandatory" if args[:name].nil? or args[:value].nil? response['Set-Cookie']="#{args[:name]}=#{args[:value]}; expires=#{args[:expires].clone.gmtime.strftime("%a, %d-%b-%Y %H:%M:%S GMT")}; path=#{args[:path]}; domain=#{args[:domain]}" end Why not? And how can I solve it? Thanks.

  • Why does SQLite take such a long time to fetch the data?

    - by Derk
    I have two possible queries, both giving the result set I want. Query one takes about 30ms, but 150ms to fetch the data from the database. SELECT id FROM featurevalues as featval3 WHERE featval3.feature IN (?,?,?,?) AND EXISTS ( SELECT 1 FROM product_to_value, product_to_value as prod2, features, featurevalues WHERE product_to_value.feature = features.int AND product_to_value.value = featurevalues.id AND features.id = ? AND featurevalues.id IN (?,?) AND product_to_value.product = prod2.product AND prod2.value = featval3.id ) Query two takes about 3ms -this is the one I therefore prefer-, but also takes 170ms to fetch the data. SELECT ( SELECT prod2.value FROM product_to_value, product_to_value as prod2, features, featurevalues WHERE product_to_value.feature = features.int AND product_to_value.value = featurevalues.id AND features.id = ? AND featurevalues.id IN (?,?) AND product_to_value.product = prod2.product AND prod2.value = featval3.id ) as id FROM featurevalues as featval3 WHERE featval3.feature IN (?,?,?,?) The 170ms seems to be related to the number of rows from table featval3. After an index is used on featval3.feature IN (?,?,?,?), 151 items "remain" in featval3. Is there something obvious I am missing regarding the slow fetching? As far as I know everything is properly indexed.. I am confused because the second query only takes a blazing 3ms to run.

  • Create a buffered image from rgb pixel values

    I have an integer array of RGB pixels that looks something like: pixels[0] = <rgb-value of pixel(0,0)> pixels[1] = <rgb-value of pixel(1,0)> pixels[2] = <rgb-value of pixel(2,0)> pixels[3] = <rgb-value of pixel(0,1)> ...etc... And I'm trying to create a BufferedImage from it. I tried the following: BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); img.getRaster().setPixels(0, 0, width, height, pixels); But the resulting image has problems with the color bands. The image is unclear and there are diagonal and horizontal lines through it. What is the proper way to initialize the image with the rgb values? thanks, Jeff

  • PHP Flatten Array with multiple leaf nodes

    - by tafaju
    What is the best way to flatten an array with multiple leaf nodes so that each full path to leaf is a distinct return? array("Object"=>array("Properties"=>array(1, 2))); to yield Object.Properties.1 Object.Properties.2 I'm able to flatten to Object.Properties.1 but 2 does not get processed with recursive function: function flattenArray($prefix, $array) { $result = array(); foreach ($array as $key => $value) { if (is_array($value)) $result = array_merge($result, flattenArray($prefix . $key . '.', $value)); else $result[$prefix . $key] = $value; } return $result; } I presume top down will not work when anticipating multiple leaf nodes, so either need some type of bottom up processing or a way to copy array for each leaf and process (althought that seems completely inefficient)

  • Combinationally unique MySQL tables

    - by Jack Webb-Heller
    So, here's the problem (it's probably an easy one :P) This is my table structure: CREATE TABLE `users_awards` ( `user_id` int(11) NOT NULL, `award_id` int(11) NOT NULL, `duplicate` int(11) NOT NULL DEFAULT '0', UNIQUE KEY `award_id` (`award_id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 So it's for a user awards system. I don't want my users to be granted the same award multiple times, which is why I have a 'duplicate' field. The query I'm trying is this (with sample data of 3 and 2) : INSERT INTO users_awards (user_id, award_id) VALUES ('3','2') ON DUPLICATE KEY UPDATE duplicate=duplicate+1 So my MySQL is a little rusty, but I set user_id to be a primary key, and award_id to be a UNIQUE key. This (kind of) created the desired effect. When user 1 was given award 2, it entered. If he/she got this twice, only one row would be in the table, and duplicate would be set to 1. And again, 2, etc. When user 2 was given award 1, it entered. If he/she got this twice, duplicate updated, etc. etc. But when user 1 is given award 1 (after user 2 has already been awarded it), user 2 (with award 1)'s duplicate field increases and nothing is added to user 1. Sorry if that's a little n00bish. Really appreciate the help! Jack
