I have a device which creates codes, and it has software to create passwords.
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?
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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
