I need some suggestions on my reimplementation Double Linked List with smart pointers since I'm new to smart pointer in C++.
I read some Doc. on smart pointers and found out there are shared_ptr, unique_ptr and weak_ptr.
I only use shared_ptr on my current code, I'm not sure how to use unique_pt...
I'm still fairly new to Django, so I feel that I may have approached this problem the wrong way. I more or less just brute forced the problem of being able to dynamically handle my form types. Additionally, I feel like some of my lines in the code to follow are a little questionable. Specifically...
This a solution to the shortest bitonic tour using dynamic programming. Bitonic tour starts at the leftmost point then goes strictly rightward to the rightmost point and finally strictly leftward to the starting point. The complexity of this algorithm is . I also use sfml to draw it (Just started...
I'm trying to replace the A,B,C, etc. with math sums and answers. I would like to know how to make say "2+3" be a match with "5"

Wrote a practice code for reversing a string say.
Input = "This is funny"
Expected output = "ynnuf si siht"
This code works for me. Want to know your comments and a better optimised way to perform this.

{
int N = input.length();

I have my own python library which gets installed wide when I do this

I wrote the following function to find the longest increasing sub-sequence in an array (tuple, it doesn't work for a list since a list is mutable and it stores the results in a dictionary.). It uses Top Down dynamic programming approach.

I don't see one of these yet, so here's the question for the proposals for the June 2016 Community Challenge! (I skipped May, as there wasn't enough time to get a good pool of suggestions.)
It's time to choose a community-challenge for June 2016.

I created a program in JavaScript that loads on a web-server (NODEJS) an HTML page, now I want to make sure that users who access can make changes (write on the page). How can i do? Thank You.
Is it possible to make this cleaner/efficient? I know that this is probably not the best way to do this and probably could be made better but i cannot figure out how i do that. Thanks for the help.

In the Concurrent Haskell Mvar documentation there is an exemple with the implementation of Skip channels
A skip channel is a pair of MVars. The first MVar contains the current
value, and a list of semaphores that need to be notified when it
changes. The second MVar is a semaphore for thi...
SOLUTION
The way to resolve this issue is by editing your System Environment Variables. In my case my System Path Variable had a string which was over 2048 characters, which apparently causes random path haywire at unpredictable times. By making sure this is below 2048 characters, it will sol...
I wrote the following code:
var xmlArray = from m in (from row in data select row.Mitarbeiter).Distinct()
select "<Value Type='Text'>" + m + "</Value>";
var xml = string.Join("",xmlArray);
Then I noticed there are two iteration (two from) and also the Distinct() and I rewrote it...

The Ruby on Rails framework doesn't allow you to validate enums submitted through a form in any sane manner. Evidently, enums are meant to be used to maintain internal application state, and are not supposed to be user-facing. Well, in my case it doesn't matter too much, but I still want validati...

I noticed that this question's title started out with "UWP", which stands for "Universal Windows Platform". Chances are such questions will become more frequent, and thus it could be useful to have a specific tag for it (like WCF and WPF etc.).
