I have two array I need to merge, and using the Union (|) operator is PAINFULLY slow.. are there any other ways to accomplish an array merge? Also, the arrays are filled with objects, not strings. An Example of the objects within the array #<Article id: 1, xml_document_id: 1, source: "<article><domain>events.waikato.ac</domain...
I cant come up with any sane solution for this problem without resorting to ridiculous combinations of custom functions. Maybe you can provide some fresh thought on this. I have the follow (simplified) array Array ( [0] => Array ( [vid_id] => 420037 [vid_rating] => 2.93827 [vid_quality] =...
I'm trying to create a utility method that will accept two arrays as parameters, merge them together, and return the resulting array. Discarding duplicates. Ideally, the parameters would accept any array type, such as int[] or string[]. I'm using C# .NET 1.1, and therefore do not have access to Generics or Array.Resize(). Is there a b...

How can I do this? In the following example, the MyData object has an array size of 5 but the MyArrayClass say only has an array size of 1....

If I do the following, it works fine: print $ref->{element}->[0]->{data}; I would like to see how many references are in the array so that I can loop through them, but I am having a hard time doing that. Here is the code I have tried, but it doesn't work: my @array = @$ref->{element}; foreach(@array) { print $_->{data}; } I ...
I had an earlier post link textwhere someone said I had my pointer initialized to the wrong element which I don't quite see why, other than they are right and it works with their correction. So here is the basic problem: If I declare an array from 0 to 30 with #define ENDPOINT 15 int record[2 * ENDPOINT + 1]; // and want a pointer to ...
I have code that sorts the way I want. By multiple fields. Cool. But now I realized that sometimes the elements could be nil. Q1: Any idea how to manage to get nil values at the top of the search? And get rid of this error message :in "<=>": undefined method "<=>" for nil:NilClass (NoMethodError) Q2: in the code below I sort by 3 elem...
I've got some problems/misunderstandings with arrays in C++. int myArray[30]; myArray[1]=2; myArray[2]=4; This is spitting out a lot of compiler errors. I don't think it is necessary to include them here as this is an easy question for everybody with experience in C(++) I guess Why doesn't this work? Is there a way to create a "dyna...

When working with arrays and pointers in C, one quickly discovers that they are by no means equivalent although it might seem so at a first glance. I know about the differences in L-values and R-values. Still, recently I tried to find out the type of a pointer that I could use in conjunction with a two-dimensional array, i.e. int foo[2]...
