Hello, I'm MelecieDiancie. I noticed that you recently removed content from Collection (abstract data type) without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; the removed content has been restored. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page.   •Melecie!•  ~talk~ 04:06, 2 May 2021 (UTC)

Hello, I'm Poojean. I wanted to let you know that one or more of your recent contributions&#32;to Double-ended queue 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. Poojean (talk) 04:08, 2 May 2021 (UTC)
