    题目描述

    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?

    输入描述:

    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.


    输出描述:

    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".

    输入例子:

    3
    Itai nyan~
    Ninjin wa iyadanyan~
    uhhh nyan~

    输出例子:

    nyan~

    分析:

    找出最长公共后缀,用gets读时先getchar读掉n后的换行符,还有加上这两行读入优化会出错。。。。。(字符串题中慎用)
