You learn by creating a solution to a problem. You learn
much less by simply reading someone else's solution.
The professor hasn't asked you to solve a problem because he/she
needs the solution. The question has been asked because solving
the question will advance your education; looking up a solution will be much less effective at that.
Education is about changing how your brain works. In mathematics,
especially, you need to work through things yourself in order to cause the brain to reorganize itself to make advancement possible.
Asking the instructor for help is better in this regard than asking someone else, say on math.SE. The reason is that the instructor can give you a hint that will help you advance, rather than a solution that won't. It may even be useful for your instructor to know that you are struggling with some ideas. You may get advice that gets you past the block. Math.SE is very unlikely to do that. The answers you likely get there will be too helpful.
Becoming a mathematician is about changes in your brain, not about
proofs printed on paper.
