Or, when a $1 denomination is used, all values can be represented. In this case, the solution is undefined, so you can return anything you like (or even loop forever).
Why is the solution undefined if a $1 denomination is used? I'd say there's an obvious answer: 0.

[Tux]: Corion++ hippo++
[ovedpo15]: it isn't homework. its a module I use at work. The process to add additional module isn't worth it. p.s never heard a university course which teach perl
[marto]: there are many, to this day.
[ovedpo15]: @Corion Yes I use the regex you showed me. its very good regex. although now i need to know that substring unit that comma
marto mad corrections to one around 18 months ago
[ovedpo15]: my code checks the value after that comma, if it isn't valid it will remove it. so I would like to remove the substring after that comma meaning getting the string before comma.
[hippo]: Are you sure that Text::CSV_XS isn't already installed at your work? It's such a useful module that it might well be there.
[marto]: pointing out the advantages of cpan modules is well worth in, as both developer and $client/$company benefit greatly
[Tux]: $src =~ m{^(.*),(.*)$/ and $2 !~ $valid and $src = $1;
[Tux]: s,/,},
