✅ How to learn data structures and algorithms?

I am trying to learn data structures and algorithms. I use neetcode.io(only free version) and Leetcode. But I don’t really have direction besides the roadmap on neetcode.io. Additionally I have a lot of questions: How many questions should I do before going to the next topic? How should I learn the topics(try to solve a problem first and then learning from the solutions, or straight up learning the topic from e.g. a YouTube video)? Are there other great recourses? I would be thankful for any advice!!! (I am really sorry for my bad English. I am not a native speaker speaker)

✅ Problem with a Recursion Function

I am currently programming a Snake-Clone and want to count the Parts(length of the tail) of the snake. Each part has a reference to the next part, called "next tail part". Is the recursion-function the problem, or something else? I am Printing the Result, by calling the function in the Debug.Log function : Console.WriteLine(DebugSnakeParts()); Function: private int DebugSnakeParts() { if(nextTailPart == null) { return 1; }else { return DebugSnakeParts() + 1; }
