一天，瓦西娅决定查看一下贝尔兰 1910 年足球锦标赛决赛的结果。不幸的是，他没能找到整场比赛的最终比分；不过，他得到了一份关于比赛过程的详细描述。该描述总共包含 $n$ 行，每行描述了一个进球。每个进球都标注了进球球队的名称。请帮助瓦西娅找出决赛的获胜球队。题目保证比赛没有平局。

The first line contains an integer n (1 ≤ n ≤ 100) — the number of lines in the description. Then follow n lines — for each goal the names of the teams that scored it. The names are non-empty lines consisting of uppercase Latin letters whose lengths do not exceed 10 symbols. It is guaranteed that the match did not end in a tie and the description contains no more than two different teams.

第一行包含一个整数 $n$（$1 \leq n \leq 100$）—— 描述中的行数。接下来是 $n$ 行，每行对应一个进球，内容为进球球队的名称。球队名称为非空字符串，仅由大写拉丁字母组成，且长度不超过 10 个字符。保证比赛未以平局结束，且描述中至多出现两个不同的球队。
