Find a line with leading and/or trailing space(s)

Create a regular expression that will find a line with leading and/or trailing space(s).

Guys, I have no idea how to start. Anyone care to lighten me up?

To see if such lines exist, you can use this simple regex (see online demo):

^ | $

To actually match the lines, use this (see online demo):

^(?: .*$|.* $)

To match a the spaces, use this (see online demo):

^ +| +$
