      In this exercise, you need to develop a function that takes a string detailing the quantity of apples and oranges 
      found in a basket which also contains mangoes. Given the string describing the count of apples and oranges and 
      an integer denoting the total amount of fruits in the basket, return the count of mangoes in the basket.
      for example:
      distribute_fruits("5 apples and 6 oranges", 19) -> 19 - 5 - 6 = 8
      distribute_fruits("0 apples and 1 oranges", 3) -> 3 - 0 - 1 = 2
      distribute_fruits("2 apples and 3 oranges", 100) -> 100 - 2 - 3 = 95
      distribute_fruits("100 apples and 1 oranges", 120) -> 120 - 100 - 1 = 19
      """
output:     def distribute_fruits(s, n):
      count_apples = int(s.split()[0])
      count_oranges = int(s.split()[3])
      count_mangoes = n - count_apples - count_oranges
      return count_mangoes
