Question

我的功能（初始化，绘制，移动和赢取）无法正常工作。任何人都可以了解我出错的地方吗？

init - 应该初始化电路板并交换1和2。
draw - 应绘制板的当前状态。
move - 如果不是非法移动，应移动瓷砖。
win - 如果按降序排列，应检查董事会。

 * Computer Science 50
 * Problem Set 3

 * Implements Game of Fifteen (generalized to d x d).
 *
 * Usage: fifteen d
 *
 * whereby the board's dimensions are to be d x d,

 *
 * Note that usleep is obsolete, but it offers more granularity than
 * sleep and is simpler to use than nanosleep; `man usleep` for more.
