To make it short: Main> let append' xs y = init xs ++ [last xs ++ [y]]
This works for the three given examples but maybe incorrect for the task you have in mind, e.g., if xs is empty. Main> append' [ [1, 2], [3, 4], [5] ] 6 [[1,2],[3,4],[5,6]] Main> append' [ ['1', '2'], ['3'] ] '4' ["12","34"] Main> append' [ [True], [True] ] False [[True],[True,False]] Cheers -- Christoph _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
