I used to post my solution if I really liked the problem.

Once I got stuck with a problem and I was going to other solutions, where I see that most of the solutions were difficult to understand and I had to spend a lot of time to actually understand the working.

I realized that just posting the solution is not doing any good to the community.

Just a request to all the coders out there to kindly put a liitle explanation of your working code.

This is my personal opinion.
