Exercise: New Apple Garden Tree |2|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

| Imagine the same garden in the question above. This time, the workers
  decide to divide the garden **vertically**. Namely, each worker will
  be responsible for the trees in a **column**.
| Write a script to find out which column produces the maximum number of
  apples in a given garden and print it.
| *Hint: You need to adjust the nested loop in the previous solution, so
  that the traverse of the garden can be column-wise.*

   Input:
   G = [[30, 40, 20, 50], [60, 20, 40, 10], [50, 30, 70, 60], [30, 40, 40, 20]]

   Output:
   [30, 60, 50, 30]

   Input:
   G = [[90, 10, 90, 40, 10], [70, 70, 80, 20, 30], [40, 60, 20, 90, 40], [40, 50, 50, 30, 20], [20, 30, 30, 80, 30], [90, 70, 20, 10, 60], [70, 90, 40, 40, 10]]

   Output:
   [90, 70, 40, 40, 20, 90, 70]
