If you take the value of N as computed in exercise 2, subtract 621,049 from it, and then take that result modulo 7, you get a number from 0 to 6 that represents the day of the week (Sunday through Saturday, respectively) on which the particular day falls.

For example, the value of N computed for August 8, 2004, is 732,239 as derived previously. 732,239 − 621,049 gives 111,190, and 111,190 % 7 gives 2, indicating that this date falls on a Tuesday.

Use the functions developed in the previous exercise to develop a program that displays the day of the week on which a particular date falls. Make certain that the program displays the day of the week in English (such as "Monday")
