有個傻X吃飽太閒，他喜歡把要留給室友的話塞在文章中讓室友自己去找，so~他室友受不了就寫程式來查囉!
把文章塞進程式，程式會自動幫你搜尋那個傻X有木有留言在文章中。
提示1:那個傻X喜歡叫室友SB，so他的留言一定是SB開頭!
提示2:留言的結尾一定是句號(英文句號呦!)
提示3:如果裡面沒傻X的留言會顯示"There is not any message!"
提示4:傻X的留言最多50個字，輸出時請考慮儲存格內原有的東西的問題~
提示5:文章一定有包括空格，一般空格會導致輸入中斷，so提供好用小涵式
fgets(str, sizeof(str), stdin);
(使用時必須指定字元陣列、大小以及 stdin,參考網址:
