If you’re copying answers so you can blow through the map and exercise with the primary goal of getting your FCC certificate within a few days or weeks, then you’re only cheating yourself. It’s your own loss.
But if you’re looking at the answers to learn, to see the pattern, to get an idea of how it was solved – AND you’re learning something new in the process, then I see nothing wrong with that.
EVERY programmer has learned from looking at other people’s code.
I don’t know where this idea came from that you’re not allowed to look at answers! So many people then get stressed by this so-called “rule”.
That would be like teaching a student how to write, without exposing him to works of great writers!
