Need Help??

Since you throw away the hash I think you can simplify the grep a little:

grep $u{ $_ }-- >0, split //, $str

de-merphq, ...I think you can simplify the grep a little I thought about that too at first but it is flawed thinking. If a letter appears more than once then it can go from 0 to a negative number which will again start returning true values. The intention was to only produce a unique list. Cheers - L~R	[reply]
