Problem Description
DT is a big fan of digital products. He writes posts about technological products almost everyday in his blog.
But there is such few comments of his posts that he feels depressed all the day. As his best friend and an excellent programmer, DT asked you to help make his blog look more popular. He is so warm that you have no idea how to refuse. But you are unwilling to
read all of his boring posts word by word. So you decided to write a script to comment below his posts automatically.
After observation, you found words “Apple” appear everywhere in his posts. After your counting, you concluded that “Apple”, “iPhone”, “iPod”, “iPad” are the most high-frequency words in his blog. Once one of these words were read by your smart script, it will
make a comment “MAI MAI MAI!”, and go on reading the post.
In order to make it more funny, you, as a fan of Sony, also want to make some comments about Sony. So you want to add a new rule to the script: make a comment “SONY DAFA IS GOOD!” when “Sony” appears.

题意分析：从所给的字符串里面找字串的问题，当时想的是用AC自动机，从网上一搜才知道用暴力求解比较简单。
