I found this question from March 2014. It's a year and a half old. In my opinion, the answers are incorrect. I'm curious as to why two others came up with the exact same solution that's different from mine. I would like to either publish the correct answer, or have my error corrected.
I have thought of posting my own solution so that I can see others' opinion of it. But I'm afraid that since the question is so old, no one will see it.
Is it considered proper protocol to pose the question again, along with my solution, and ask for input?
