这个程序使用了一个 4x4 的数组来表示游戏板，其中数字 0 表示空格。程序开始时，调用 initialize() 函数初始化游戏板，然后调用 add_random_num() 函数添加两个随机的数字。之后，程序进入一个循环，在每次循环中，程序读取用户输入的移动方向，然后调用相应的函数来移动数字。如果移动了数字，程序调用 add_random_num() 函数添加一个随机数字，然后打印游戏板。当玩家达到目标数字 2048 时，程序会打印出“Congratulations! You won!”的消息并退出游戏。如果玩家不能再移动数字，程序会打印出“Game over. Try again.”的消息并退出游戏。
