  While I&nbsp;am writing this post, typhoon signal number 8 is hosting. But the weather isn't too bad, and it's cool. Anyway, this typhoon isn't very strong, I hope nobody would get hurt under this typhoon. &nbsp; By the way, I finally understand quicksort.
I can explain every step of quicksort now. This algorithm in fact is very easy, the code is&nbsp;easy&nbsp;to write, and have a high efficiency. The next step is to read through the algorithm and implementation again, to get a more thorough understanding. &nbsp; Next month is a critical time for me. The release of HKCEE result has a great affection to me as it is going to determine whether I can study F. 6 and where will I study. I hope everything will be fine and I can have a wonderful life with my friends in STMGSS.
