CF2172A.ASCII Art Contest

Three leading AI-powered creative assistants—Gemini, ChatGPT, and Claude—enter the first ever ASCII Art Contest, where they must impress a panel of human judges with their text-based masterpieces.

Each participant receives a score between 80 and 100 (inclusive). The organizers want to announce the final standing only if the judges' opinions are "close enough"; otherwise, they will ask the judges to reconsider.

Given the three integer scores of Gemini, ChatGPT, and Claude, determine the contest result:

• If the maximum score and the minimum score differ by at least 10 points, print check again (the judging seems inconsistent, so the panel must re-evaluate).
• Otherwise, print final X, where X is the median of the three scores (the score that would be in the middle if all three were sorted in non-decreasing order).

三款领先的AI创意助手——Gemini、ChatGPT 和 Claude——参加首届 ASCII 艺术大赛，它们需以纯文本形式创作出杰作，打动人类评委团。

每位参赛者获得一个介于 80 到 100（含）之间的整数分数。主办方仅在评委意见“足够接近”时才公布最终排名；否则，将要求评委重新审议。

给定 Gemini、ChatGPT 和 Claude 的三个整数分数，请判定比赛结果：

• 若最高分与最低分之差至少为 10 分，则输出 check again（表明评分不一致，评委团必须重新评估）；
• 否则，输出 final X，其中 $X$ 是这三个分数的中位数（即三个分数按非递减顺序排序后位于中间位置的分数）。

A single line contains three integers $g, c, \ell$, representing the scores of Gemini, ChatGPT, and Claude respectively.

• $80\le g, c, \ell \le 100$

一行包含三个整数 $g, c, \ell$，分别表示双子座（Gemini）、ChatGPT 和 Claude 的得分。

• $80\le g, c, \ell \le 100$
