Question

-Could you please define the following functions and test them in a haskell by using a bag module:

1)newBag returns a new bag with no elements (i.e., empty).

2)isEmpty takes a bag and returns True if the bag has no elements and returns False otherwise.

3)isElem takes an element and a bag and returns True if the element occurs in the bag and returns False otherwise.

4)size takes a bag and returns its cardinality (i.e., the total number of occurrences of all elements).

5)occursBag takes an element and a bag and returns the number of occurrences of the element in the bag.

please finf below the code : i have only solve for 1,2,3,4,

1 :

2 :

Output: True if bag is empty

3: elemBag :: Eq a => a -> Bag a -> Bool

4 : lengthBag :: Bag a -> Int
