Regex to get everything but last word in sentence of words seperated by “/“?

Question

What would be the appropriate regex to get everything of a sentence except the final word:

For example:

/hello/world     -> /hello/
/one/two/three   -> /one/two/
/foo/bar/ice/tea -> /foo/bar/ice/

Answer 1

use this regular expression ^/.+/

Answer 2

(.+)\b\w+$

This is fine for all sentences. No matter whether it has / or not.
