  • Sort months ( with strings ) algorithm

    - by Oscar Reyes
    I have this months array: ["January", "March", "December" , "October" ] And I want to have it sorted like this: ["January", "March", "October", "December" ] I'm currently thinking in a "if/else" horrible cascade but I wonder if there is some other way to do this. The bad part is that I need to do this only with "string" ( that is, without using Date object or anything like that ) What would be a good approach?

  • Simple PERL Problem

    - by Suezy
    I have an array of numbers: @numbers = 1,2,3,6,8,9,11,12,13,14,15,20 and I want to print it this way: 1-3,6,8-9,11-15,20 Any thoughts? Of course I tried using the most common "looping", but still didn't get it.

    Hello, with the hash below, I would like the clients array's reference : my $this = { 'name' => $name, 'max_clients' => $max_clients, 'clients' => () }; I can't do "\$this{'clients'};" to retrieve the reference.

  • Counting comma seperated values in php,how to?

    - by Jay
    Hey folks, I have a variable holding values separated by a comma (Implode), I'm trying to get the total count of the values in that variable however, count() is just returning 1. I've tried converting the comma separated values to a properly formatted array which still spits out1. So heres the quick snippet where the sarray session equals to value1,value2,value3: $schools = $_SESSION['sarray']; $result = count($schools); Any help would be appreciated.

  • Is this the correct way to build a Perl hash that utilizes arrays?

    - by Structure
    This is the first time I have manipulated hashes and arrays in this way -- and it is working. Basically, for every key there are multiple values that I want to record and then print out in the form "key -- value -- value -- val..." My code is as follows. I am surprised that it works, so concerned that it works "by mistake". Is this the correct way to accomplish this task, or is there a more efficient or appropriate method? while ($source =~ m/(regex)/g) { #Get all key names from source $listkey = $1; #Set current list key to the current regex result. $list{$listkey} = ++$i unless $list{$listkey}; #Add the key to the hash unless it already exists. $list{$listkey} = [] unless exists $list{$listkey}; #Add an array for the hash unless the hash already exists. while ($loopcount==0) { if ($ifcount==0) { $listvalue=result_of_some_function_using_list_key; #Get the first list value from the list key. $ifcount++; #Increment so we only get the first list value once. } else { $listvalue=result_of_some_function_using_list_value; #Update the last list value. } if ($listvalue) { #If the function returned a value... push @{$list{$listkey}}, $listvalue; #...then add the value to the hash array for the key. } else { #There are no more values and we need a new key. $listkey=0; #Reset variable. $domain=0; #Reset variable. $loopcount++; #Increment loop counter to exit loop. } } $ifcount=0; #Reset count variable so the next listvalue can be generated from the new key. $loopcount=0; #Reset count variable so another loop can begin for a new key. } foreach $listkey (keys %list) { #For each key in the hash. print "$listkey --> "; #Print the key. @values = @{$list{$listkey}}; #Reference the arrays of the hash. print join ' --> ', @values; #Print the values. print "\n"; #Print new line. }

  • Counting number of values between interval

    - by calccrypto
    Is there any efficient way in python to count the times an array of numbers is between certain intervals? the number of intervals i will be using may get quite large like: mylist = [4,4,1,18,2,15,6,14,2,16,2,17,12,3,12,4,15,5,17] some function(mylist, startpoints): # startpoints = [0,10,20] count values in range [0,9] count values in range [10-19] output = [9,10]

  • how does array_diff work?

    - by SpawnCxy
    I just wonder how array_diff() works.And obviously it couldn't work as follows function array_diff($arraya, $arrayb) { $diffs = array(); foreach ($arraya as $keya => $valuea) { foreach ($arrayb as $valueb) { if ($valuea == $valueb) { break; } $diffs[$keya]=$valuea; } } return $diffs; } //couldn't be worse than this Hope someone can show me some better solution. Thanks.

  • Why does display:table-cell not center content without display:table?

    - by Samuel
    I'm looking for the most efficient (or elegant) way to vertically and horizontally center content of variable height. I've come up with this: http://cssdeck.com/t/2veysdkg/16, which uses css tables to vertically center the main content. My demands for writing this particular piece of code were: Must be able to center variable and fixed width content vertically and horizontally Centered content must be inside the normal document flow (so no overlapping) Sticky footer and normal header of 100% width As few hacks, ugly code or non-semantic html as possible I didn't care about support for IE6, IE7 (I'll use a different stylesheet for them) The weird thing is that the demands above are only met when the header and footer are set to table-row, and the body-tag to display:table. Which is weird because as I understand it the css will generate anonymous table elements when parent table elements are missing. So table-cell should work without all the surrounding elements, but yet I've not been able to make it work. If it were up to me I would prefer to not mess with the display mode for the body tag, and leave the header and footer on display:block. But I've not been able to make it work. Does anyone understand why this doesn't work?

  • Verifying method with array passed by reference using Moq

    - by kaa
    Given the following interface public interface ISomething { void DoMany(string[] strs); void DoManyRef(ref string[] strs); } I would like to verify that the DoManyRef method is called, and passed any string array as the strs parameter. The following test fails: public void CanVerifyMethodsWithArrayRefParameter() { var a = new Mock<ISomething>().Object; var strs = new string[0]; a.DoManyRef(ref strs); var other = It.IsAny<string[]>(); Mock.Get(a).Verify(t => t.DoManyRef(ref other)); } While the following not requiring the array passed by reference passes: public void CanVerifyMethodsWithArrayParameter() { var a = new Mock<ISomething>().Object; a.DoMany(new[] { "a", "b" }); Mock.Get(a).Verify(t => t.DoMany(It.IsAny<string[]>())); } I am not able to change the interface to eliminate the by reference requirement.

  • Returning a byte array from activex to javascript

    - by vondip
    Hello all, I've built a small activex control using c#. I've got a function that returns an array of bytes. From some reason when I try to consue the returned array in js I receive an undefined value. Why is this happenning? Is there anyway to solve it? Here's a simple demonstration of my code: Activex: [ComVisible(true)] public byte[] Close() { try { MessageBox.Show("called from activex Close"); return Stop(); } catch (Exception e) { //ExceptionHandling.AppException(e); throw e; } } Javascript Call: function CloseActiveX(){ var myRslt = document.OurActiveX.Close(); }

  • converting between struct and byte array

    - by chonch
    his question is about converting between a struct and a byte array. Many solutions are based around GCHandle.Alloc() and Marshal.StructureToPtr(). The problem is these calls generate garbage. For example, under Windows CE 6 R3 about 400 bytes of garbarge is made with a small structure. If the code below could be made to work the solution could be considered cleaner. It appears the sizeof() happens too late in the compile to work. public struct Data { public double a; public int b; public double c; } [StructLayout(LayoutKind.Explicit)] public unsafe struct DataWrapper { private static readonly int val = sizeof(Data); [FieldOffset(0)] public fixed byte Arr[val]; // "fixed" is to embed array instead of ref [FieldOffset(0)] public Data; // based on a C++ union }
