I have a dynamic array myArr. What is stored in the memory in myArr when we use SetLength on it? Is it '00'? Or undefined? SetLength allocates 16 bytes of memory for myArr in this case. myArr : array of byte; SetLength(myArr, 16); ...

I am trying to sort an array which has properties like it increases upto some extent then it starts decreasing, then increases and then decreases and so on. Is there any algorithm which can sort this in less then nlog(n) complexity by making use of it being partially ordered? array example = 14,19,34,56,36,22,20,7,45,56,50,32,31,45.......

Assume we have three arrays of length N which contain arbitrary numbers of type long. Then we are given a number M (of the same type) and our mission is to pick three numbers A, B and C one from each array (in other words A should be picked from first array, B from second one and C from third) so the sum A + B + C = M. Question: could w...

I query the database as follows my $sth = $dbw->prepare($sql); while (@rows = $sth->fetchrow_array()) { ... ... } Now, I need to create a hash such that rows[0] is the key and rows[1],rows[2],rows[3] are the values. For each record read, a new h...
In other languages like C++, you have to keep track of the array length yourself - how does Delphi know the length of my array? Is there an internal, hidden integer? Is it better, for performance-critical parts, to not use Length() but a direct integer managed by me? ...
Hello! I’d like to do this: static const int size = 5; @interface Foo { char bar[size]; } But the compiler complains that “instance variables must have constant size”. Do I really have to #define the size, or is there a way to get it work with a regular constant? (I’d like the memory to be allocated statically, no malloc.) ...
I created a image uploader which works by remote, so whenever a user enters a bunch of links, I want to prevent duplicate links being added so that the image isn't copied twice and is removed so it leaves the links to be unique without any duplicates. $break = explode("\n", $links); $count = count($break); $unique_images = array(); fo...

I am trying to create a 'mask' of a numpy.array by specifying certain criteria. Python even has nice syntax for something like this: >> A = numpy.array([1,2,3,4,5]) >> A > 3 array([False, False, False, True, True]) But if I have a list of criteria instead of a range: >> A = numpy.array([1,2,3,4,5]) >> crit = [1,3,5] I can't do this...
Let's say I have a function called MyFunction(int myArray[][]) that does some array manipulations. If I write the parameter list like that, the compiler will complain that it needs to know the size of the array at compile time. Is there a way to rewrite the parameter list so that I can pass an array with any size to the function? Edit...

Hi, I have a sorted list of ratios, and I need to find a "bin size" that is small enough so that none of them overlap. To put it shortly, I need to do what the title says. If you want a little background, read on. I am working on a graphical experiment that deals with ratios and the ability of the eye to distinguish between these ratios...
Code below takes a directory and creates an array of folder names appearing under the directory.

First off, I know my title can be formulated better, but my math classes are so far gone I can't remember the correct words anymore.. I need to do something like this (pseudo c#) int[] digits1 = new int[10]{0,1,2,3,4,5,6,7,8,9}; int[] digits2 = new int[10]{0,1,2,3,4,5,6,7,8,9}; int result = digits1*digits2 This would be the sum of th...
