Haskell List of tuples to list?

Question

Is it possible to convert a list of tuples [(Int,Int)] as a generic way which valid to any input size ? .. i saw in various questions thats its not possible gen

Answer 1

You could also use a fold and avoid explicit recursion:

tupleToList = foldr (\(f,s) a -> f : s : a) []

Or:

tupleToList = foldl (\a (f,s) -> a ++ [f,s]) []

(For elements of the same type)
