< p > 汉诺塔问题源自一个古老的传说。在古印度的一个寺庙里，僧侣们有三根高大的钻石柱子，以及 < span class = "arithmatex" > \(64\)< / span > 个大小不一的金圆盘。僧侣们不断地移动圆盘，他们相信在最后一个圆盘被正确放置的那一刻，这个世界就会结束。< / p >
2023-08-29 20:57:26 +08:00
< p > 然而，即使僧侣们每秒钟移动一次，总共需要大约 < span class = "arithmatex" > \(2^{64} \approx 1.84× < / span > 秒，合约 < span class = "arithmatex" > \(5850\)< / span > 亿年，远远超过了现在对宇宙年龄的估计。所以，倘若这个传说是真的，我们应该不需要担心世界末日的到来。< / p >
