7-118 估值一亿的AI核心代码 (20 分)
以上图片来自新浪微博。
本题要求你实现一个稍微更值钱一点的 AI 英文问答程序,规则是:
- 无论用户说什么,首先把对方说的话在一行中原样打印出来;
- 消除原文中多余空格:把相邻单词间的多个空格换成 1 个空格,把行首尾的空格全部删掉,把标点符号前面的空格删掉;
- 把原文中所有大写英文字母变成小写,除了
I
; - 把原文中所有独立的
can you
、could you
对应地换成I can
、I could
—— 这里“独立”是指被空格或标点符号分隔开的单词; - 把原文中所有独立的
I
和me
换成you
; - 把原文中所有的问号
?
换成惊叹号!
; - 在一行中输出替换后的句子作为 AI 的回答。
输入格式:
输入首先在第一行给出不超过 10 的正整数 N,随后 N 行,每行给出一句不超过 1000 个字符的、以回车结尾的用户的对话,对话为非空字符串,仅包括字母、数字、空格、可见的半角标点符号。
输出格式:
按题面要求输出,每个 AI 的回答前要加上 AI:
和一个空格。
输入样例:
6 Hello ? Good to chat with you can you speak Chinese? Really? Could you show me 5 What Is this prime? I,don 't know
输出样例:
Hello ? AI: hello! Good to chat with you AI: good to chat with you can you speak Chinese? AI: I can speak chinese! Really? AI: really! Could you show me 5 AI: I could show you 5 What Is this prime? I,don 't know AI: what Is this prime! you,don't know
