分析

  • 这个就是分类讨论细致些,比如巨长的change(int n)的讨论。一个 subscript 写错就有可能造成 bug。每一个方向分别两步走:1. 先将空位取消,移动到一端。 2.再判断相邻连个是否相等,在进行输出(此处我又写了2个function)和加分。
  • 胜负判断为随机的一个数无法加上去(即没有空位,全部填满)。
  • 其他与之前的几个类似,分析见 贪吃蛇游戏移动迷宫游戏
  • 修改说明(2020.09.08)
    程序经试验(同学玩的时候发现的)发现存在bug,如下图:
    bug
    于是回到程序中寻找,发现169,170,307,308行有错误。
    下面改好又试验了以下:
    (就是输出示例的图)
    为了保险起见,决定做一下计算。
    CK2
    先不考虑自动生成4的情况,此时每个数字对应得分是可以算出来的,然后这样算出的数字减去程序中算出的总分,可求出大致的操作数为245(因为每7次生成一次4),这是差不多的。因而程序基本上不存在bug了。
