Need Help??

I'll get things started here. I don't have time for the extra credit, but this solves the first part:

sub t_in_s {
($t=pop)=~s/./$&.*/g;$_[0]=~$t
}

t_in_s('abcdefghijklmnopqrstuvwxyz', 'for');
[download]

Although, if $t may contain non-word characters, that becomes:

sub t_in_s {
($t=pop)=~s/./\Q$&\E.*/g;$_[0]=~$t
}
[download]

If $s or $t can contain \n, you need a /s on both matches. But your $_[0] can be replaced with pop. That makes your solution turn into the 36 character: `sub t_in_s { ($t=pop)=~s/./\Q$&\E.*/gs;pop=~/$t/s }` [download] or 38 if you wish to add my to make it strict compliant.	[reply] [d/l]

I realized later that I had the replacement in the wrong order, and I could save two characters: `sub t_in_s { ($t=pop)=~s/./.*\Q$&/gs;pop=~/$t/s }` [download] So that's 34 characters.	[reply] [d/l]
