Re: Perl Golf Proposal

[cLive ;-)]

sub i{$_=<>;chop;if(/^\d{1,4}$/){return sprintf("%04d",$_)}print"!\n";
+&i}$c=i;$d=i;for($c..$d){$_="bar$_.jpg";print"$_\n"unless(-e)}

Enter first then last in sequence. no check made that second number is larger than first (not in challenge :))

! means re-enter digit

131 chars (includes 'bonus' challenge).

Hmmm, that was fun :)

cLive ;-)

Update: if larger strings *are* valid as long as they are numerically correct, the above needs amending to:

sub i{$_=<>;chop;if(/^\d+$/&&$_<10000){return sprintf("%04d",$_)}print
+"!\n";&i}$c=i;$d=i;for($c..$d){$_="bar$_.jpg";print"$_\n"unless(-e)}

adding another 6 chars...
