What you need to do is put multiple regular expressions into String#gsub
method by first calling Regexp::union. At each match you need to find
out
which regular expression did the match and provide it with the
replacement
string. So you need to use this version of gsub:
str.gsub(pattern) {|match| block } => new_str
