L1-064 估值一亿的 AI 核心代码
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：
tex

Good to chat with you

Really?
Could you show me 5
What Is this prime? I,don 't know6
