Great! Clear and easy to understand~ It's so cool to solve the problem just in 1 line without any complicated structures.

Great! So cleaver! So that the solution don't need to check if it's an empty array.

Clear and creative. The solution with sets and binary bitwise operations? Thanks, I've really learned from your code.

Although I don't understand, it's simple and great! Loop in a line and creating list?
