solving coding system
I have a device which creates codes, and it has software to create passwords.
for example:
1. if 003472BL-2345 then the password is 2DD6
2. if 003473BL-2345 then the password is EC57
3. if 000000XX-2345 then--F9B5
4. if 003470BL-2222 then A8CF
I tried to decode its code many times, but I could not resovle it.
What kind of coding system is it using?
best regards,

Re: solving coding system
Hi kanykey;
That looks like a problem posted here by redrooster. I'm working on his, no solution yet.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
