When I saw a post discussing the algorithm, I suddenly remembered what was the PASCAL. The "data structure" of the green skin is still placed on the bookshelf, and occasionally takes out. I really miss the experience of the crazy learning. Like now, you can go online. At that time, I couldn't find a Pascal compiler. In the bag, there are a few box floppy dishes, stuffed with a variety of tools, and feel that the world seems to be on the feet. Later, there was a "data structure" of the C language version, but I can't find it.
