  Hello, and welcome to Wikipedia! I edit Wikipedia too, under the username Metricopolus. I noticed that one of your recent edits, such as the one you made to Binary tree with this edit, appeared to be unconstructive, and I’ve reverted it. In the future, please use the sandbox for testing and be sure to provide an informative edit summary. You may also wish to read the introduction to editing. Please feel free to ask me questions about editing Wikipedia (or anything else) on my talk page. Metricopolus (talk) 03:29, 2 October 2011 (UTC)Reply
