Problem Description:

Zeller$$s 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$/4+5$j$)\%7$

where

$-$ h is the day of the week $(0$: Saturday, $1$: Sunday, $2$: Monday...$)$

$-$ 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$)$

$-$ 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.
