@UnrelatedString I want to prompt with a >>, then read a single line.

looks really hard tbh

trying to check if a substring is in a GET request: Try it online!

ok, I realized the URL was wrong: Try it online!

but is still gives me a 403 for somereason

does jelly have matrices? if so, is there a short way to get all submatrices?

jelly has matrix operations on 2d arrays

but i don't think there's a builtin for submatrices

so it would be a matter of getting all sublists of the rows, then for each sublist of rows getting every sublist of columns
