Hi
f1 :: [Int] -> [[Int]]
f1 [] = []
f1 (a:as) = [a] : f1 as
f1 is simply a map
f3 la lb = let a = head la
b = head lb
in if sum a <= sum b then
a : f3 (tail la) lb
else
b : f3 la (tail lb)
Why not use pattern matching to split up la and lb, rather than head/tail?
I would have thought the whole function could be written as a nice
foldr merge, where merge :: [Int] -> [Int] -> [Int]. Thats only a
guess at the top of my head though, not worked out properly.
Is this homework? If so its useful to state when you post the question :)
Thanks
Neil
