I don't know exactly what is wrong with your code. I read it and the idea seems correct. Maybe there's something not working as expected in between all those variables and conditionals.

I implemented a similar idea and got accepted. Here is my code for reference, maybe it'll help you: C++ Code

      I always use unordered_set when I don't need the elements to be ordered. Here, I just needed to check how many different elements there were, so unordered_set is the way to go.
