This would be following a lesson on regex (using perl syntax)
In the following code snippet:
“foo bar 123 bar23 foo baz” =~ /(.+?s){3}..(.+)s/;
what would be the result in $2 (the second captured group)?
a) o
b) r23 foo
c) r23
d) bar23
How would one capture the expression “123” from that same string?
