shell小游戏 猜数字
时间:2014-02-20 03:30 来源:chinaunix.net 作者:chinaunix.net
生成的密码和用户输入可以接受重复数字
所以相对一般规则的猜数字可能难度要大不少
本版本规则:
A--数字对,位置也对
B--排除A的结果后,数字对,但位置不对
开始后,系统化初始化一个4位可重复数字,如“1223”。假设用户第一次输入“1234”,那么系统将提示“2A1B”,前两位数字“12”相同并且位置也相同,为“2A”。后两位数字中,用户输入的“3”与密文中“3”相同,但两者位置不同,则为“1B”,最终结果为“2A1B”。
再假设用户此时输入“1232”,那么结果则为“2A2B”,计算方法与前次一样。
代码如下
