  • Recursive powerof-function, see if you can solve it

    - by Jonas B
    First of all, this is not schoolwork - just my curiousity as I for some reason can't get my head around it and solve it. I come up with these stupid things all the time and it annoys the hell out of me when I cant solve them. Code example is in C# but solution doesn't have to be in any particular programming-language. long powerofnum(short num, long powerof) { return powerofnum2(num, powerof, powerof); } long powerofnum2(short num, long powerof, long holder) { if (num == 1) return powerof; else { return powerof = powerofnum2(num - 1, holder * powerof, holder); } } As you can see I have two methods. I call for powerofnum(value, powerofvalue) which then calls the next method with the powerofvalue also in a third parameter as a placeholder so it remembers the original powerof value through the recursion. What I want to accomplish is to do this with only one method. I know I could just declare a variable in the first method with the powerof value to remember it and then iterate from 0 to value of num. But as this is a theoretical question I want it done recursively. I could also in the first method just take a third parameter called whatever to store the value just like I do in the second method that is called by the first, but that looks really stupid. Why should you have to write what seems like the same parameter twice? Rules explained in short: no iteration scope-specific variables only only one method Anyhow, I'd appreciate a clean solution. Good luck :)

  • How to pass checkbox array to Java from jsp

    - by eddy
    Hi, I'd like to know if there's any way to send data to the server for the selected rows using the checkboxes I've put on those rows? I mean , how can I send only the data of those selected rows to the server? Here's the html code I use: <table> <thead> <tr class="tableheader"> <td width="10%"></td> <td width="30%">Vehicle</td> <td width="40%">Driver</td> <td width="10%">Mileage</td> </tr> </thead> <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectedItems" value="c:out value="${item.numberPlate}"/>"/> </td> <td align="left"><c:out value="${item.numberPlate}"/></td> <td align="left"><c:out value="${item.driver.fullName}" /></td> <td align="left"><input type="text" name="mileage" value="" /></td> </tr> </c:forEach> </tbody> </table> I really hope you can give some guidance on this. Thanks in beforehand.

  • How to stop Django from adding extra html elements to rendered widgets.

    - by stinkypyper
    I have a Django radio button group that renders to HTML as follows: <ul> <li><label for="id_package_id_0"><input type="radio" id="id_package_id_0" value="1" name="package_id" /> Test 256</label></li> <li><label for="id_package_id_1"><input type="radio" id="id_package_id_1" value="2" name="package_id" /> Test 384</label></li> <li><label for="id_package_id_2"><input type="radio" id="id_package_id_2" value="3" name="package_id" /> Test 512</label></li> <li><label for="id_package_id_3"><input type="radio" id="id_package_id_3" value="4" name="package_id" /> Test 768</label></li> <li><label for="id_package_id_4"><input type="radio" id="id_package_id_4" value="5" name="package_id" /> Test 1024</label></li> </ul> I need it to render without being a list. I am a aware of form.as_p, form.as_table, and form.as_ul. They will not help me as they continue to add extra HTML tags. As well, I am not using the form object in it's absolute entirety, just for validation. I am doing a custom template for the form already, but wish to continue to the radio widget.

  • Invoking a function call in a string in an Oracle Procedure

    - by DMS
    Hello, I writing an application using Oracle 10g. I am currently facing this problem. I take in "filename" as parameter of type varchar2. A sample value that filename may contain is: 'TEST || to_char(sysdate, 'DDD')'. In the procedure, I want to get the value of this file name as in TEST147. When i write: select filename into ffilename from dual; I get the value ffilename = TEST || to_char(sysdate, 'DDD') whick makes sense. But how can I get around this issue and invoke the function in the string value? Help appreciated. Thanks.

  • Best Functional Approach

    - by dbyrne
    I have some mutable scala code that I am trying to rewrite in a more functional style. It is a fairly intricate piece of code, so I am trying to refactor it in pieces. My first thought was this: def iterate(count:Int,d:MyComplexType) = { //Generate next value n //Process n causing some side effects return iterate(count - 1, n) } This didn't seem functional at all to me, since I still have side effects mixed throughout my code. My second thought was this: def generateStream(d:MyComplexType):Stream[MyComplexType] = { //Generate next value n return Stream.cons(n, generateStream(n)) } for (n <- generateStream(initialValue).take(2000000)) { //process n causing some side effects } This seemed like a better solution to me, because at least I've isolated my functional value-generation code from the mutable value-processing code. However, this is much less memory efficient because I am generating a large list that I don't really need to store. This leaves me with 3 choices: Write a tail-recursive function, bite the bullet and refactor the value-processing code Use a lazy list. This is not a memory sensitive app (although it is performance sensitive) Come up with a new approach. I guess what I really want is a lazily evaluated sequence where I can discard the values after I've processed them. Any suggestions?

  • Python finding substring between certain characters using regex and replace()

    - by jCuga
    Suppose I have a string with lots of random stuff in it like the following: strJunk ="asdf2adsf29Value=five&lakl23ljk43asdldl" And I'm interested in obtaining the substring sitting between 'Value=' and '&', which in this example would be 'five'. I can use a regex like the following: match = re.search(r'Value=?([^&>]+)', strJunk) >>> print match.group(0) Value=five >>> print match.group(1) five How come match.group(0) is the whole thing 'Value=five' and group(1) is just 'five'? And is there a way for me to just get 'five' as the only result? (This question stems from me only having a tenuous grasp of regex) I am also going to have to make a substitution in this string such such as the following: val1 = match.group(1) strJunk.replace(val1, "six", 1) Which yields: 'asdf2adsf29Value=six&lakl23ljk43asdldl' Considering that I plan on performing the above two tasks (finding the string between 'Value=' and '&', as well as replacing that value) over and over, I was wondering if there are any other more efficient ways of looking for the substring and replacing it in the original string. I'm fine sticking with what I've got but I just want to make sure that I'm not taking up more time than I have to be if better methods are out there.

  • Lookup function not working (RS SP2)

    - by Al Reyes
    Hi, I made the upgrade to SP2. I'm trying to use the Lookup function to link data from two different servers. I'm trying first a simple exercise linking data from two datasets from the same server, having one dataset with journals and the other with the account description. My Expression looks like this at a field on the table I have: =Lookup(Fields!ACTINDX.Value,Fields!ACTINDX.Value,Fields!ACTDESCR.Value,"ACCTINFO") I made sure of the names and using only uppercases for datasets and fields but I'm receiving the following message when I try to preview: "An error occurred during local report processing. The definition of the report '/DETAIL' is invalid. The Value expression for the text box 'ACTINDX' refers to the field 'ACTDESCR'. Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope". I'll appreciate any suggestions. Regards, Al

  • Objective-C Passing a variable to another IBAction

NSString *myVariable; - (IBAction) doFirstAction { myVariable = [imageNode getAttributeName:@"value"]; } - (IBAction) doSecondAction { NSLog(@"%@",myVariable); } Any clue as to why I cant access myVariable outside of doFirstAction?

  • jQuery Ajax loads URL multiple times, how do I unbind/rebind properly?

    - by gmoz22
    I load a SELECT element via Ajax (list of brands), get its selected value (brand id) and load another SELECT via another Ajax URL (list of templates for currently selected brand). Here's my code: $(document).ready( function() { // DO NOT cache Ajax calls $.ajaxSetup ({ cache: false }); // loader var ajax_load = "Loading..."; // Brands List URL var loadBrandUrl = "getBrandsList.php"; // Templates List URL var loadTemplateUrl = "getTemplatesList.php"; $("#brandslistSelect").html(ajax_load).load(loadBrandUrl) .ajaxComplete(function(){ // Brands select loaded /* Load Templates SELECT the first time since no .change() has happened */ var selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value console.log(selectedBrand); // Log selected brand to console // get Templates select, commented for now since it does an infinite loop // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); /* End initial load template */ /* On interaction with the Brands SELECT */ $("#brandslistSelect").change(function () { // on interaction with select selectedBrand = $("#brandslistSelect option:selected").attr("value"); // get the value // get Templates SELECT $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ) }); /* End interaction with the Brands SELECT */ }); }); It returns selectedBrand in the console 3 times : selectedBrand = undefined selectedBrand = undefined selectedBrand = 101 Now, if I uncomment the following line, same output as above but it also loads the templates URL indefinitely : // $("#templateslistSelect").html(ajax_load).load(loadTemplateUrl, { BrandId: selectedBrand } ); Any idea how I could modify this code to make it work as intended? Thanks for your help stackOverflow community!

  • Automatic Data sorting/ analysis in Excel

    I have data in the form of four columns. The first three columns represent time, value1, value 2. The fourth column is binary, all 0's or 1's. Is there a way to tell excel to delete time, value1 and value 2, when the corresponding binary value in column four is 0? I know this is a lot easier in C++ or matlab, but for reasons beyond my control, I must do it in excel.

  • perl - converting a date into a string
