Answer 2

In the challenges it will be great if you can test the code when you see the answers :) i mean sometimes i dont get it even if i see the answer, and when i try to write the code in a IDE i get so much errors and i wonder how that code work(and i dont mean it like i forget some library or smth like that)
Or it will be great if you get some sword of explain :p i know this can be too much, but a noobie like me will be very happy :D
