With the great help of the editor-in-charge, the book was put on the shelves. Of course, it is to encourage the shelves, but even if it is to encourage the shelves, Octave is very important, after all, this is the first book of Octave to hit the shelves. As you can see, the results of this book are so poor that there is no piracy. Alas, this also means that if the book friend wants to really chase my books, he will have to spend money. Because, this book may not even be pirated. Of course, now that it's on the shelves, it's a responsibility, and if the book friend subscribes to my chapter, even if it's only one subscription, I'll update it, because at least someone is reading it. Not to mention anything else, I hope you can give a first order, thank you eight times here, thank you again.
