Today, in the community of 9CBS, see a post, feel good.
The question asked the problem of this applet of the Russian square, a high person called Xiao Xianmei (once again, if it is MM, I have a chance to see the exchange, it is best to mention a "word model". Solution, a complex problem with a bit is extremely simple, and the problem of processing processing is changed to the processing of matrices. This is very big for my programming idea. I used to think about what algorithms. I always think according to the way, as long as I can realize, regardless of the programs (that is, the overhead of the program), only, only occasional optimization . I really should learn some algorithms or programming skills of previous programmers. This graphical problem collected today is the idea of "word mode" in digital issues, as a starting point for my collection of early programming ideas. I believe that the collection of these ideological algorithms can make my ideas a lot.
