P9973 [THUPC 2024 Preliminary] You Are Right, But AIGC

You are right, but **this problem does not accept providing hack testdata.**

You are right, but as everyone knows, AIGC is one of the hottest directions in computer science right now. Several members of the computing association are also very interested in it. After a long period of hard work, they finally developed a brand-new large language model, ChatSAA. You are right, but when the model was about to be released, the development team suddenly found a major issue: because one team member was addicted to a **game with a two-character Chinese name and a seven-letter English name (see the sample)**, the corpus used to train the model was somehow polluted. As a result, every sentence generated by the model comes with the same prefix. You are right, but it is obviously too late to urgently switch the corpus and retrain. Helplessly, the team could only note in the documentation that the model’s biggest **feature (not a bug)** is the **first 19 characters** of the generated text. This is not only the model’s unique anti-counterfeiting mark, but also fully shows the computing association team’s humanistic spirit and cultural literacy. You are right, but there is a tiny problem: this makes it obvious at a glance which sentences are generated by AI, which is very unfriendly to students who plan to use AI to write homework. You are right, but now you have some sentences. Some are generated by ChatSAA, and some are written by humans (assume humans did not deliberately imitate ChatSAA’s generation feature). You need to write a program to tell them apart.

You are right, but your program should read one line, a string $s$ representing the sentence to judge. It satisfies $|s| \le 200$, and $s$ consists of ASCII visible characters including spaces (i.e., characters with ASCII codes in $32\sim 126$).

You are right, but your program should output one line, a string representing the judgment result. If the sentence is generated by AI, output `AI`; otherwise output `Human`.

### Explanation for Sample \#1 You are right, but Minesweeper (Winmine) is a game with a two-character Chinese name and a seven-letter English name. ### Hint You are right, but if I say this problem statement was generated by AI, how would you respond? Translated by ChatGPT 5
