• Problem 1 (89 poits): Write a function count_abc that has 3 parameteres: 2D list of characters, row size and col size. The function finds and returns the number of times letter a appears in the 2D list, the number of times letter b appears in the 2D list, and the number of times letter c appears in the 2D list. Write a program that randomly generates a 2D list of characters. The program uses function count_abc to count the number of occurrences of a, b and c in the 2D list.

• Problem 2 (11 points): Write a function: sum_col that has 3 parameteres: 2D list of integers, row size and col size. The function finds and returns the sum of elements in each COLUMN.
