Today's update is late because of the keyboard.

I don't know what's going on these two days. Some keys either don't appear when you press them once, or several symbols appear.

Even the minus sign has this problem.

So that my code word speed plummeted, and I was a handicapped party, which made it worse.

But I have already bought a new keyboard on JD.com, I just don't know when it will arrive.

I will try my best to code these two days.

But if the code is too slow, there may only be two changes tomorrow and the day after tomorrow.

But if there are two more changes, the missing ones will be made up later.

So don't worry.

So thank you again for your support, thank you!
