Random_Walk,

A minor nit. If I've understood the code correctly, you've used a substitution...

$days = s/+//;

...where a transliteration would be "better"...

$days = tr/+//d;    # Note transobliteration modifier

...and a lot faster (not that this is really an issue in this case.)Unless you wanted to allow only a leading + in which case...

$days = s/^+//;

Elgon

It is better wither to be silent, or to say things of more value than silence. Sooner throw a pearl at hazard than an idle or useless word; and do not say a little in many words, but a great deal in a few.

    You are right tr would have been more efficient for what I did but I really should have put s/^+//; to follow the principle of least surprise so that 2+3 would be rejected rather than converted to 23

    Cheers,
    R.
