I'm following along with the 'Regular Expressions in JavaScript' course. How can I match 'ladybug' and 'fading rug!' only using the '?', '.' and '[]' special RegEx characters? It should be possible with these alone but I can't figure it out. Thanks :)

[lf]ad[yi]n?g? ?[br]ug!?
And here's another one that is more concise (and less exclusive) using only . and ?:
.ad.n?g? ?.ug!?
