In your first example, 5A2C74CD74, there are the consecutive characters 'C' and 'D'.

We'll have to hear from the OP to decide this question.
Security experts discourage repeat characters because such passwords are insecure. A person whose "lucky number" is 7 might be tempted to establish a password such as 7777777777. For that matter, the easy-to-remember password 1234567890 is also insecure.
If your interpretation is correct, that makes this programming task more challenging.
Should we also prohibit downward increments such as 9876543210? How about "flip-flop" passwords such as 6969696969?
