Hello. I think your approach with using gsub is not the best possible
here. It's better to simply find the matching part using match and
substitute it for the whole string, like this:
place1 = string1.match(/(\d+)th\b/)[1]
The \b ensures that the next character after 'th' is not a word
character (\b is word boundary), and [1] at the end is extracting the
first bracketed group. It also makes it possible to skip the .* at both
ends, which is a bit ugly.
Apart from that, a useful piece of knowledge about regexps:
/.*?(\d+)th.*/ will match what you want, because the first .*? will be
reluctant to eat up more characters, so it will pass to \d+ as many
digits as it can.
TPR.
