Hello, I'm Bestagon. An edit that you recently made to Collection (abstract data type) seemed to be a test and has been reverted. 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! Bestagon ⬡ 02:16, 29 October 2021 (UTC)
