I know that a lot of people discourage looking at solutions before coming up with one yourself, but I think it can be an efficient way of studying.
To be honest, if you're like me and your thinking is still a little stiff and it's hard for you to wrap your mind around complex algorithms, reading the solutions is not a bad idea. Some of the members here write some very clear and descriptive solutions!
I feel like my thinking isn't quite flexible enough to think of more efficient solutions sometimes and reading on how other people approach problems can be a great way to train your mind to think differently.
Of course just reading isn't enough! Make sure to try and implement that solution or something similar on your own without looking!
