Hello, I'm David Eppstein. An edit that you recently made to Logarithm seemed to be a test and has been removed. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! —David Eppstein (talk) 07:33, 4 May 2020 (UTC)
