I went through this thread but it doesn't answer my question entirely. My question is a little different.
I want to post a problem I've already solved for the sole purpose of watching how others solve it or what insights or techniques other people may provide. After posting the question, I would like to post my solution as an answer, so that my solution is open to voting as well. This way I can know what the community feels about my solution. I can find out whose solution is the most elegant one as per the community.
In other words, I want to post a question not to ask for help but to have fun and to learn from others. Is this a good thing to do in math.se?
