能帮帮忙啊啊!泪奔了我都TT
i have so many four digit code numbers to remember that i cannot keep them all in my head. the bank say you should not write down your personal identification numbers(PINs)for cash and credit card and keep them in a wallet with the card .so i can findout what the numbers are,i have devised a code which should be complicated enough to confuse any thief who steals my wallet. i code all the numbers using 1=A,2=Bup to9=I,0=J. then i write the coded numbers down backwards so 1234 is written DCBA. finally at the end of each coded number i add an extra letter between A and J to say what that particular code is of : C is for credit card: F is for phone card: B is for bicycle lock
combination : E is for my Eastern Bank card and D is for my Denton Building Society card.
My list looks as follows:
A D G E F
C J D B E
B G F A C
G J A C D
D F G C B
what is my bicycle lockcombination?
A.4673
B.5741
C.7613
D.4356
E.3764
要是有谁能帮这个忙!小女!万分感谢啊啊啊啊啊啊啊!急!TT

答案是A

B =bicycle lock combination
再问： 谢谢啦！！！！能不能具体一点点~TT
再答： 真是够笨，26个字母按顺利代表数字1-26，A是1，B是2，依此类推…。最后一个字母代表密码的用途(B就表示自行车锁的密码)。
再问： = =! 那是A 还是E 阿~~有两个答案啊啊啊啊TT
再答： 我漏看了一点，应该还要倒一下，答案是E，千真万确，真是无聊的题目。
