魔兽密保卡效果，精通数组的大虾请进！
[free] 我想做一个类似魔兽密保卡的系统：密保卡如下但我的数组学的不好，哪位高人帮忙解决下
所要效果如下
登录账号时随即生成6个字母 比如 AEBDHF
那吗需要用户从密保卡上找到对应的数字填入才能验证成功登录
验证是先找行再找列 AEBDHF 对应的数字为115432
A B C D E F G H I J K L M N
A 11 12 13 14 15 16 17 18 19 20 21 22 23 24
B 25 26 27 28 29 30 31 32 33 34 35 36 37 38
C 39 40 41 42 43 44 45 46 47 48 49 50 51 52
D 53 54 55 56 57 58 59 60 61 62 63 64 65 66
E 11 12 13 14 15 16 17 18 19 20 21 22 23 24
F 25 26 27 28 29 30 31 32 33 34 35 36 37 38
G 39 40 41 42 43 44 45 46 47 48 49 50 51 52
H 53 54 55 56 57 58 59 60 61 62 63 64 65 66
我想应该是用二维数组吧
很紧急 高手帮忙 小弟不甚感激

左边也有列字母
要想找到唯一的数字必须根据横坐标和纵坐标找交叉点吧
产生的字母是先根据横坐标（也就是行）和纵坐标（也就是列）产生的
比如产生的ED 意思就是先在行上找到E再在列上找到D 他们相交的那个数就是要验证的数 57 这个简单呀，上面二维数组存放就不多说了。
你用随机产生的6位字母作为拆分，如AEBDHF，AE BD HF，
又因为你的A是列，E是行，
然后利用二重循环，查找。
唯一不同的是二维数组是比如a[5][1],这时你可以定义一个枚举变量来保存
A-Z。这样的话就可以查值了
比如a[5][1]，可以用a[e.e][e.a]来代替,明白了吧 //问题描述
//有时间正确 有时间取不到随即数 有时间数组索引超出范围 竟然能取到z 我实在看不出来 请高手帮助
