Welcome, D4.
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.
Note: Backticks are not single quotes.
Also, here is a potentially useful discussion on the topic of recursion: Replace Loops using Recursion -1 explanation
Hope this helps
