比赛地址：阴间 CTF 2025 比赛时间：4 Apr 2025 14:44 CST - 6 Apr 2025 14:44 CST Misc 阴曹地府税务总局 Challenge 近年来，阴曹地府面临财政赤字，阎王爷特批成立了 "阴曹地府税务总局"，专门对阳间烧给亡灵的冥币收税。然而，由于地府税务系统采用了一套基于 Python 随机数的税率波动算法，导致税率每时每刻都在变化，甚至有时会出现 "零税率" 的情况。 作为一名资深会计师，你在阳寿未尽时不慎掉入阴曹地府。为了回到阳间，你需要向地府税务总局贿赂足够的冥币，获取一张特殊通行证。但你需要预测税率波动，在低税率或零税率时交易，才能最大化你的有限资产。 hint: python Solution “基于 Python 随机数的税率波动算法” 那多半就是 random 库了 “每时每刻都在变化” 说明随机数的种子是时间戳 手动玩一遍发现服务器会在一开始就先给出 10 个税率，那么我就可以枚举近期的时间戳，然后通过对比找到正确的时间戳，进而推测出未来的税率，代码如下 12345678910111213141516171819202 ...
