The Japanese language is notorious for its sentence ending particles. Personal preference of such particles can be considered as a reflection of the speaker's personality. Such a preference is called "Kuchiguse" and is often exaggerated artistically in Anime and Manga. For example, the artificial sentence ending particle "nyan~" is often used as a stereotype for characters with a cat-like personality:
- Itai nyan~ (It hurts, nyan~)
- Ninjin wa iyada nyan~ (I hate carrots, nyan~)
Now given a few lines spoken by the same character, can you find her Kuchiguse?
Input Specification:
Each input file contains one test case. For each case, the first line is an integer N (2<=N<=100). Following are N file lines of 0~256 (inclusive) characters in length, each representing a character's spoken line. The spoken lines are case sensitive.
Output Specification:
For each test case, print in one line the kuchiguse of the character, i.e., the longest common suffix of all N lines. If there is no such suffix, write "nai".
Sample Input 1:
3 Itai nyan~ Ninjin wa iyadanyan~ uhhh nyan~
Sample Output 1:
nyan~
Sample Input 2:
3 Itai! Ninjinnwaiyada T_T T_T
Sample Output 2:
nai

转眼之间，我转行已经7个月了，自学了4个月，试用了3个月，总算顺利的转正成功了。算是正式迈向了程序员的道路上。如果恰好你也是转行看到我这段话，我希望你不要担心，低下头往前走，就行了。心里的焦虑，不安，都会随着时间，流去。努力下，时间会给你想要的答案。
转行而已，不简单，也不难。因为是在国企，下班有足够的学习时间，这段时间刷完了pat，再去刷TCP/IP,数据结构和算法。再补一补C++的模板类范例编程之类的吧。感觉工作中，这种用的都不是太多。
