Modify the PROGRAM 4 so that it also satisfies the following two additional Requirements:

REQUIREMENT 1:When validating user input for hours used, account for the month and year the charges are being computed for.

REQUIREMENT 2:Display how much money Package A customers would save if they purchased packages B or C, and how much money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed.

Demonstrate test cases described in table:

Test Case Package Hours Month Year

1 A 49 11 2019

2 a 720 09 2019

3 A 730 06 2019

4 a 99 04 2019

5 B 100 12 2019

6 b 744 10 2019

7 B 745 08 2019

8 c 672 02 2019

9 C 673 02 2019

10 c 696 02 2020

11 C 697 02 2020

Clearly identify the results of each test case.
