Haskell Language Lists List Concatenation
Example
listA = [1, 2, 3]
listB = [4, 5, 6]
listAThenB = listA ++ listB -- [1, 2, 3, 4, 5, 6]
(++) xs [] = xs
(++) [] ys = ys
(++) (x:xs) ys = x : (xs ++ ys)
listA = [1, 2, 3]
listB = [4, 5, 6]
listAThenB = listA ++ listB -- [1, 2, 3, 4, 5, 6]
(++) xs [] = xs
(++) [] ys = ys
(++) (x:xs) ys = x : (xs ++ ys)
