Answer 2

challenges are solely a means to challenge your memory, no other benefit besides xp really. you don't learn much from it.
the solutions are shown after your opponent is done, they aren't explained however. if you ever feel confused you can ask about it here or do some research about it, it helps a lot. :D

Answer 3

well, it will improve your confusion with the programming and give you confident for quick answering enthusiasum.

more than that you understand the things properly by challenges.
