The input is given as three integers representing the daymonth and year respectively.
Return the answer as one of the following values {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}.

Example 1:
Input: day = 31, month = 8, year = 2019

Example 2:
Input: day = 18, month = 7, year = 1999
