Java Date and Time 

Problem

The Calendar class is an abstract class that provides methods for converting between a specific instant in time and a set of calendar fields such as YEAR, MONTH, DAY_OF_MONTH, HOUR, and so on, and for manipulating the calendar fields, such as getting the date of the next week.

Here you are given a date. You just need to write the method, getDay, which returns the day on that date

As for example, if you are given the date , the method should return  as the day on that date.

Input Style

A single line of input containing the space separated month, day and year, respectively, in  MM DD YYYY  format.

Constraints

2000<year<3000

Output Style

Output the correct day in capital letters.

Sample Input

08 05 2015

Sample Output

WEDNESDAY

Explanation

The day on August 5th 2015  was WEDNESDAY.
