Can someone please review my solution and advise a better solution to convert each character in a string to Array excluding any character (i.e , / ; -). The solution I have applied is below but I am sure it can be simplified. Many thanks in advance.

I have written a function to calculate all strong components in a graph.
How do I make this cleaner and nicer?

I recently solved Advent of Code 2019 Day 6 in C#.
Part 1:
You've landed at the Universal Orbit Map facility on Mercury. Because
navigation in space often involves transferring between orbits, the
orbit maps here are useful for finding efficient routes between, for
example, you and San...
I was given a Perl script that should be executing a linux command that performs a diff on two files:

my($file2) = shift;

I'm writing a game server, recently I found a bug which happens when two requests coming to my server at the same time.
Here is the method:

{
if (game.Winners.Count < game.MaxWinners)

I've this sample list which has nodes and their neighbors if they have any. The problem is to find the node which has the highest number of neighbors.
neigh = [['A'],['A','B'],['A','C'],['B','D'],['C','A']]
The neighbor are calculated in both directions. Example: ['A','B'] are neighbors to eac...
Basic idea is to use a Class, with static methods to add and remove references in a static vector, that keeps track of these references, and check that vector upon exit.
The class is detecting intentional leaks that I create, but maybe you can find a case where it does not detect the leak, that ...
I have a little problem, I wouldn't know how to sort a String list. I don't want to sort it alphabetically, I want to sort it from highest to lowest or from lowest to highest.
String line = "hello" + "world" + "54";
String line1 = "red" + "color" + "895";
String line2 = "blue" + "col...
My VBA code currently loops for 5,000 iterations and takes about 25 minutes to collect the output data in the Output excel sheet. Is there a way to reduce the time taken for instance by improving the copying and pasting of values, collecting the output data in some kind of array etc.? Given that ...
I am an old python newbie here, migrating from fortran77 ;)
Still unsure of the python terminology at the moment :(

Just for fun, I created a script called TinyBF which can compress Brainfuck programs into a format half their size. For example, take a famous hello world program clocking in at 78 bytes:
--<-<<+[+[<+>--->->->-<<<]>]<<--.<++++++.<<-..<<.<+.>>.>>.<<<.+++.>>.>>-.<<<+.
When put into TinyBF format...

I have a fair few years experience with programming, and am currently working in a software development role, writing internal web applications in C#.
This is the first C++ code I have ever written, so I therefore don't know the conventions, code smells, do's/don't's of the language.

new to multithreading. I wrote this program which should be a solution to the producer-consumer problem. The problem is that both a producer and a consumer end up in the waiting state. What seems to be wrong? (And everything else what is wrong ^_^) Thanks in advance.

I will only address the question "Should titles reference external resources", to which I believe the answer is:
Yes. It's perfectly acceptable to reference external resources in titles.
If I see the title "Advent of Code Day 5", I might already know exactly what that question is about as I mys...
