Good job on solving the problem, Jim. You wonder where to post the solution?
The truth is, there is no way for someone other than the problem author to submit an official solution. You can post them in the comments, but it won't say SOLUTION POSTED on the problem itself.
Eventually though, you can see the official solution. Just keep checking in the "Recently Posted Solutions" below the list of the most recent problems on the homepage.
