Given a date, it is possible to determine the day of the week for that date using the following algorithm (use integer division throughout) .Let y be the 4-digit year, m be a 2-digit value corresponding to the month (for example, for March m-3, and for November m-11), and d be the 2-digit day. If m is equal to 1 or 2 then reduce y by 1 Set p equal to the last two digits of y Set q equal to the first two digits of y Setr-((m+9) mod 12)+1 Set s (13r-1)/5 . Set t-p/4 Set u-q/4 . Set w y mod 7. The day of the week is given by the value of w, where w would be Sunday. Write a Python program, in a file called day_of_week.py, to implement this algorithm asking the user for the year, month and day (each in the form of a numerical value). Your program should include the following functions: getDayName(d) returns a string representation of integer day d .getMonthName(m) - returns a string representation of integer month m .getDayNum(y,m, d) returns the value of w as above . main() Your output should be formatted as below Sample output 1: Enter the 4-digit year: 1992 Enter the month as an integer: 1 Enter the day as an integer: 14 anuary 14, 1992 is a Tuesday Sample output 2 Enter the 4-digit year: 2008 Enter the month as an integer: 8 Enter the day as an integer: 22 August 22, 2008 is a Friday
