生死狙击炎魔

说明：  这是一个很有用的编程小程序，希望能给大家以借鉴(This is a very useful programming program, I hope you can learn from it.)

编译原理转逆波兰式-compiler theory to reverse Polish

说明：  aksub support file for installation

这两天在网上看到一张让人涨姿势的图片，图片中展示的是贪吃蛇游戏， 估计大部分人都玩过。但如果仅仅是贪吃蛇游戏，那么它就没有什么让人涨姿势的地方了。 问题的关键在于，图片中的贪吃蛇真的很贪吃XD，它把矩形中出现的食物吃了个遍， 然后华丽丽地把整个矩形填满，真心是看得赏心悦目。作为一个CSer， 第一个想到的是，这东西是写程序实现的(因为，一般人干不出这事。 果断是要让程序来干的)第二个想到的是，写程序该如何实现，该用什么算法？ 既然开始想了，就开始做。因为Talk is cheap，要show me the code才行。 

本代码是基于labview的UDP点对点通信程序，已经在局域网内测试通过-The code is based on the LabVIEW UDP peer-to-peer communication program has been tested in the LAN
