Problem Description

Chikami Nanako is a girl living in many different parallel worlds. In this problem we talk about one of them.
In this world, Nanako has a special habit. When talking with others, she always ends each sentence with "nanodesu".
There are two situations:
If a sentence ends with "desu", she changes "desu" into "nanodesu", e.g. for "iloveyoudesu", she will say "iloveyounanodesu". Otherwise, she just add "nanodesu" to the end of the original sentence.
Given an original sentence, what will it sound like aften spoken by Nanako?

 

Input

The first line has a number T (T <= 1000) , indicating the number of test cases.
For each test case, the only line contains a string s, which is the original sentence.
The length of sentence s will not exceed 100, and the sentence contains lowercase letters from a to z only.

 

Output

For every case, you should output "Case #t: " at first, without quotes. Thet is the case number starting from 1. Then output which Nanako will say.

 

Sample Input

2ohayougozaimasudaijyoubudesu

 

Sample Output

Case #1: ohayougozaimasunanodesuCase #2: daijyoubunanodesu

题意：水题。额，只要看最后几位是否满足这种情况，如果不满足的话直接加上这个字符。否则将前面几个字符给删掉，然后继续加。
