**3.21 Science: day of the week. Zellers congruence is an algorithm developed by Christian Zeller to calculate the day of the week. The formula is

h=(q+26(m+1)/10+k+k / 4+j / 4+5j)% 7

where

h is the day of the week (0: Saturday, 1: Sunday, 2: Monday, 3: Tuesday, 4: Wednesday, 5: Thursday, 6: Friday).

q is the day of the month.

m is the month (3: March, 4: April, , 12: December). January and February are counted as months 13 and 14 of the previous year. So, you need to convert the users input 1 to 13 and 2 to 14 for the month.

j is the century (i.e., year / 100).

k is the year of the century (i.e., year % 100).

Note that the division in the formula performs an integer division. Write a program that prompts the user to enter a year, month, and day of the month, and displays the name of the day of the week. Here are some sample runs:

CLASS NAME: Your program should be called ZellersCongruence.java

Specifications:

1.Use scanner and input data from the keyboard.

2.Display title above and your name below.

3.Use given equation above to calculate the day.
