This may be a long winded way of doing it, but what about this?
1.Dump all your arrays in to a hash to get frequency of the letters 2. Rebuild array comparing original array element and hash key, and checking if value is < 1 then that element is undef. Unless I've misunderstood what you want, doesn't that do what you're after?
