How to get the last directory in a line?

Question

Regular Expressions

You need to get the last directory from the link (it doesn’t matter if it’s a link or just a string)

Example:

https://site.ru/catalog/cat1/ you need to get cat1
https://site.ru/catalog/cat1/cat2/ you need to get cat2
https ://site.ru/catalog/cat1/cat2/cat3/ you need to get cat3
https://site.ru/catalog/cat1/cat2/cat3/cat4/ you need to get cat4

This means that the nesting is different, it can be like 1, and 10+, but you need to pull out the last one.

/(?:.(?!/))+$ everything works after the last one/
