Hello, I'm David Eppstein. I wanted to let you know that one or more of your recent contributions&#32;to Time complexity have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks. —David Eppstein (talk) 05:23, 26 June 2021 (UTC)
