Use Excel spreadsheet to conduct Decision Table-Based Testing for the following problem. A calendar program gives an answer either Correct or Incorrect for the following given inputs. The program currently only has the ability to check these two years: year = 2020, year = 2021. The answer should be Incorrect if the year is out of bound. For a given year, the program can evaluate three sets of months: month {1, 3, 5, 7, 8, 10, 12}, month {4, 6, 9, 11}, month {2}. For a given month, the program can check the number of days: days = 31, days = 30, days = 29, or days = 28. Please submit your decision table with the lowest number of test cases to achieve full coverage.

Condition: year = 2020

Condition: year = 2021

Condition: month {1, 3, 5, 7, 8, 10, 12}

Condition: month {4, 6, 9, 11}

Condition: month {2}

Action: days = 31

Action: days = 30

Action: days = 29

Action: days = 28
