kudra XP is just a number  Comment on   Given a (long) string
$s, and a test string $t.  Find for perl golf a subroutine to
determine if the characters of $t are in $s, not necessarily
consecutive but in order, returning true if so, false if not.
For example, if $s = "abcdefghijklmnopqrstuvwxyz", then the sub
should return true for $t = "for", but not $t = "perl".  For
extra credit, have the sub return undef if the string isn't
found, and the remainder of $s minus those characters of $t that
were matched, with the remaining characters in the same order,
if $t was in $s.   In reply to Golf: Embedded In Order by Masem
