How about no.
Seriously, first of all its against the forum policy to post uncommented solutions and after all I don’t consider it that much helpful either. The exercises are rather short so in the end they all look pretty similar and if you couldn’t figure out the difficulty beforehand chances are good you will still not find it when comparing you’re code to “the solution”. Also this often leads to a copy&paste pass without grasping the necessary knowledge. Also the whole idea of programming is kind of like:
You have a task, some requirements and a tool set of option to pick from. Solve the task and fulfil the requirements. Good Luck!
So first of all there might not even be “the solution” but a whole bunch of ways that work (more or less) and also solving puzzles and making mistakes is part of the progress. It’s not something evil but almost inevitable and might even enhance your understanding if you find out why something is wrong.
