解析

题目不难，就正则替换一下就行。

要注意一下（已在代码中用注释说明）：

1
can I can you

can I can you
AI: can you I can

AC Code

public static void main(String[] args) throws Exception {
    int n = nextInt();
    while(n-- != 0) {
        String text = br.readLine();
        String person = text;
        text = "";
        for(int i = 0; i < person.length(); i++) {
            char ch = person.charAt(i);
            if(ch != 'I') text += String.valueOf(ch).toLowerCase();
            else text += ch;
        }

        text = text.trim();
        text = text.replaceAll("\\s+", " ");

        // 加 “ _ ” 是为了防止与 I me 替换成 you 发生冲突
        text = text.replaceAll("\\bcan you\\b", "_I can");
        text = text.replaceAll("\\bcould you\\b", "_I could");

        text = text.replaceAll("\\bI\\b|\\bme\\b", "you");

        text = text.replaceAll("\\?", "!");
        text = text.replaceAll(" !", "!");
        text = text.replaceAll(" \\?", "?");
        text = text.replaceAll(" \\.", ".");
        text = text.replaceAll(" '", "'");
        text = text.replaceAll(" ,", ",");

        text = text.replaceAll("_I", "I");

        //text = text.replaceAll("\b_I\b", "");
        out.println(person);
        out.printf("AI: %s\n", text);
    }
    out.flush();
}
