This pit is no longer in use, so you don't need to continue collecting it.
Because the exam was messy in the previous period, I forgot my password when I went online in July, so I applied for an account and opened a new pit. But now I accidentally found the password I had written down in the math book... I am too lazy to continue revising. It is troublesome for everyone to see and for me.
So, now I am going to rewrite this article, the address is below, please support me and continue to support me! Thanks!
Hmm... Guaranteed update speed this time (laughs
