贪吃蛇算法,稍微有点不同于网上的。网上的都是把蛇身的所有节点都储存了下来。

数据结构， 不复杂

给个保存蛇头蛇尾地址。还有保存方向的。然后用队列（先进先出表）保存拐点

-This algorithm is slightly different　the Snake online. Internet is the snake all nodes are stored down.

Data structure is not complex

Save snakeheads to a tail address. There are saving direction. Then save the inflection point with a queue (FIFO table)
