Re: Is there a way to compare strings without using an array?

in reply to Is there a way to compare strings without using an array?

I need a little bit of clarification. Is this a correct interpretation of your question?

given two strings
find all duplicate characters
order of matches is not important

This also looks homeworkish. If so, please state as much. In any case, please show what you have tried.

Yes, that is correct and no it isn't a hw problem. I have individual protein families, each containing a various number of proteins. These proteins are not unique to a protein family. They can be in many families. I'm trying to find the best way to perform total protein coverage with the least number of protein families. I'm using a greedy algorithm. Instead of storing all 5million (rough guess) or so proteins in an array and checking them off once I've retrieved them I would like to put them in a really long string to save some space. I haven't tried using a string yet, because I've been working with a hash array combination.	[reply]

In which case, have you looked at BioPerl yet? It might have more tools that you'll be interested in. There's a large community at www.bioperl.org perl -e 'print qq(Just another Perl Hacker\n)' # where's the irony switch?	[reply]
