/************************************************************************************************************************
文件名称：main.c
文件描述：实现控制台的2048逻辑代码
编译环境：vs2015
最后修改：
<2017.1.8> <最后一次修改23:38 依然存在算法上的问题，在上下左右当中> <修改者：PorYoung>
<最近修改：2017.1.9 算法问题待定，另发现生成2和4时存在bug，整体有待优化><修改者：PorYoung>
<优化思路：①代码优化，减少函数个数；②功能优化：增加撤销功能，自动走一步功能；③算法优化：生成算法优化、移动、加法优化>
