After the noon call, I originally planned to code the words well and code a few more, but the second one was halfway through the writing and stuck.

I've been stuck until now, and I don't have a clue, it's miserable.

Work the direction, and if the thinking can be straightened out, it will be updated as soon as possible, but if you can't, you can only wait for tomorrow to make up for it...... (To be continued......)
