Anyone has any top list in terms of most interesting/creative/fun? Because, I find most of these tasks quite boring - even if the solution is not clear from the start, it just feels too contrived and you know that it's aimed at some particular algorithm and the data structure.

I am really enjoying working through the book "Elements of Programming Interviews"

Instead of Leetcode I'd recommend starting off with Firecode.io. It's a lot more structured and there's a lot of bells and whistles included in the package that make solving these problems fun.
