哈希函数是密码学中的重要工具,它能够将任意长度的输入数据映射到一个固定长度的输出值，这个输出值通常被称为哈希值或哈希码，哈希值的长度（即位数）是衡量哈希函数性能的重要指标之一，了解哈希值的位数，不仅有助于我们更好地理解哈希函数的工作原理，还能在实际应用中发挥重要作用。

我们将通过一个有趣的游戏来探讨哈希值的位数,这个游戏不仅能锻炼我们的逻辑思维能力，还能帮助我们更深入地理解哈希函数的特性。

游戏规则

1. 选择一个哈希函数：我们需要选择一个具体的哈希函数，比如SHA-256、SHA-384等，这些哈希函数的输出长度是固定的，例如SHA-256的输出长度是32个字节，即256位。

2. 生成哈希值：我们随机选择一个输入字符串，通过选定的哈希函数对其进行哈希处理，得到一个哈希值。

3. 隐藏哈希值的位数：将生成的哈希值的位数隐藏起来，只显示哈希值本身。

4. 猜测游戏：玩家需要根据显示的哈希值，猜测其位数，如果猜测正确，玩家获胜；否则，继续猜测，直到正确为止。

游戏流程

1. 初始化：假设我们选择的是SHA-256哈希函数，其输出长度为256位，我们随机选择一个输入字符串，Hello World!”，并对其进行哈希处理，得到一个256位的哈希值。

2. 隐藏位数：将哈希值的位数隐藏起来，只显示哈希值本身，假设生成的哈希值为：
