: → MoneyChain:真猛的法官啊... 218.187.108.215 04/29 11:43
: 推 BillHuang:用费氏数列真是厉害啊! 163.25.118.31 04/29 12:13
: 推 indiana:前两个字母"J","A"还可以解释,第三个"C"是 59.121.216.192 04/29 13:38
: → indiana:怎麽来的呢? 59.121.216.192 04/29 13:39
1.并非单纯是Fibonacci numbers,而是Fibonacci numbers各项减一
...As the first two letters then, "J" and "A" remain unchanged because
they are tied to the Fibonacci numbers 1 and 1. From then on in the
judge's code, the alphabet shifts down one place - so the E becomes
D - (representing the Fibonacci 2), and then two places (representing
the 3) and then four places (representing the 5)and so on for each of
the following letters. ...
2.法官故意放了四个错误字母进去混淆视听
...Because of four errors - which the judge claims are deliberate - ...
让解出来的文字变成
"Smithy Code: Jadkie Fisthr- who are bou? Dreadqought".
(正确应该是"Smithy Code Jackie Fisher Who Are You Dreadnought)
3.因此解法应该是:
----------------------------------------------------------------------------
法官密码 J A E I E X T O
字母顺序(A) 10 1 5 9 5 24 20 15
谜底 J A D(C) K I E F I
字母顺序(B) 10 1 4 11 9 5 6 9
(A.B)顺序差异 0 0 1 2 4 7 12 20
此数列各项+1就是Fibonacci no.
Fibonacci no. 1 1 2 3 5 8 13 21
---------------------------------------------------------------------------
PS:顺序并非两者相减,而是按照固定方向两字母差异,例如X和E差异不是24-5=19,而是
X→Z=2,A→E=5,2+5=7
PS2:可是我发现,从XTO之後,好像规则又不太符合了 @.@
PS3:比起这个,还是无畏舰和费雪上将比较有趣 @.@
PS4:
http://0rz.net/b21iW 这篇文章是破解者写的
作者所说,这个破解的大部分过程是法官好心提供的
PS5:法官还发现作者本身也是cryptology的专家,幽了作者一默
... The judge then pronounced his verdict on my cryptology skills. "If you
can't solve this now you should be sacked," he said. ...
