Personally, the problem is not difficult, but it is not to say that the title can be high. It is also the most C test, becoming an excellent programmer, and is completely different from the hard work of a software worker under the framework of software engineering. C language is not because of this language, he is only important, I think it is, because the algorithm, the data structure is also through the C language. The general software level is relatively high, it is good, in fact, I think it is, they learn C, learn the data structure and algorithm. I think the programmer is Coding. . . . . . Read the program ----> Change the program -----> Write a program yourself. What we have to learn is the algorithm.
