Haskell Programming

--6. Using a list comprehension, define a function grid :: Int -> [(Int,Int)] that returns a

-- list of all (x, y) coordinate pairs on an n X n square grid, excluding the diagonal

-- running from (0, 0) to (n, n). For example,

--

-- ghci> grid 2

-- [(0,1),(0,2),(1,0),(1,2),(2,0),(2,1)]
