Could I ask you to evaluate my solution to Unisex Bathroom problem?
I tried to solve also a starvation issue and I think I succeeded.
Besides all what is the necessity of semaphores that the problem is related to? Why can’t size be simply compared to capacity as I did?

I am reverse engineering a game server binary as a hobby project and noticed they use the thread-per-connection approach, this way:

Feel like I went about this the wrong way, but my gut said to check if a number divided evenly by each number up to 20 and when it did, return it.

for (d = 1; d <=20; d++) {
if (number % d === 0) {
continue;

I have this little exercise writing a binary trie in F#. In C# it can be done in few lines, but here it became more complicated than I had expected (especially the add function):

I'm writing a function to stringify a nested struct. I'm using snprintf to pre-calculate how much space I'll need to allocate.
The problem is, it's extremely repetitious, and will only get worse if I ever need to add more fields to any of the structs. The duplication also creates more of an oppo...
