As a disclaimer, those problems are weird enough to convince anyone that they are not school or uni work or something.
This is a huge misconception about site policies. We don't care if a question comes from school, assigned homework, or from your own thoughts.
The policy in regards to exercises is that you don't just post the exercise and ask for a solution. Ideally, your question wouldn't reference an exercise at all and would be purely about the concepts you would need to understand in order to solve the problem on your own. Of course, this isn't always possible, and so the next best thing is to use the exercise only to frame the context of your question. The goal should always be understanding the concepts, not looking for a worked solution or calculation.
So to answer the question
Is it OK to ask for a solution here...
without further information, I'm going to say no.
