Automatons

Let say, we have a finite automaton defined as: Failed to parse (syntax error): {\displaystyle (Q, &Sigma; , q_0, F, &delta; )}

type Transition = (Int, Char, Int)
type Automaton = (Int, String, [Int], Int, [Transition ])

where states are coded with numbers from 0 to n

ex1 :: Automaton 
ex1 = (3, [0], [2], "ab", [(0,'a',1), (0,'b',0), (1,'a',1), (1,'b',2), (2,'a',1), (2,'b',0)])

ex2 :: Automaton 
ex2 = (3, [0], [2], "ab", [(0,'a',1), (0,'a',0), (0,'b',0), (1,'b',2)])
  • Create a function, that sorts an array using quicksort algorithm quicksort. Inside, you must use the mutable array STArray.
quickSort :: Array Int Int -> Array Int Int
ghci> elems $ quickSort $  listArray (0,5) [8,4,9,6,7,1] 
[1,4,6,7,8,9]
