Hello, I'm Roost. An edit that you recently made to Disjoint sets seemed to be a test. 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! RoostTC (ping me!) 23:47, 12 December 2022 (UTC)
