找1~n中的完全平方数
I’v been wanting to optimize my blog’s loading speed for a long time. However, even when I rewrote my theme, I still didn’t do it.
Recently, while trying to accelerate my blog load speed, I also want to get all my pictures a cdn. Also I’m tired of uploading the picture every time I want to quote a picture in my post, So I found a softeware PicGo.
This problem derives from Heap Sort.
