Inclusive vs. Exclusive Array Slicing
Raw
arrayslice.elm
-- subArray - Take two Ints, i and l, and an Array and returns an Array with length l starting at index i
subArray : Int -> Int -> Array a -> Array a
subArray i l = slice i (i + l - 1)
-- slice' - Exclusive slicing (breaks negative indices)
slice' i j = slice i (j-1)
subArray' i l = slice' i (i + l)
take' = slice' 0
--take1 is like take, but operates on hypothetical 1-indexed arrays.
take1 = slice 1
