最近情报人员得到了一些经过加密的文章，每个单词都很长。破译人员想到先把单词化简一下，方法是吧每个单词尽量取短些的前缀，但所有的前缀不能是其它单词的前缀。这个任务现在就交给你来完成。

解释：“字符串s1 是s2的前缀”是说把字符串 s2的后面去掉某些，只保留与 s1相同长度时， s2就与 s1完全相同。如“ abc”是“ abcaade”和“ abc”的前缀，但不是“ ababc”的前缀。

单词数N,1≤N≤50；每个单词长度不超过50；并且单词都由小写字母构成。保证所给单词没有一个单词是另一个单词的前缀。

输入文件：

第一行一个整数N，表示单词个数。

下面N行，每行一个单词。

输出文件

共N行，每行一个单词，是对应上面的N个单词化简后的单词。-Recent intelligence officers got some encrypted article, each word is very long.
