Problem:
 Score : 100 points    Problem Statement In some other world, today is December D -th.  Write a program that prints Christmas if D = 25 , Christmas Eve if D = 24 , Christmas Eve Eve if D = 23 and Christmas Eve Eve Eve if D = 22 .      Constraints  22 \leq D \leq 25  D is an integer.         Input Input is given from Standard Input in the following format:  D       Output Print the specified string (case-sensitive).        Sample Input 1 25      Sample Output 1 Christmas       Sample Input 2 22      Sample Output 2 Christmas Eve Eve Eve  Be sure to print spaces between the words.
