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 in $\{1,3,5,7,8,10,12\},$ month in $\{4,6,9,11\},$ month in $\{2\}.$ 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.
