Problem A. Alaska Don't Release Them
*****
Given that Queen cards are wild, what is the formal definition of five cards in consecutive sequence? I see four reasonable interpretations:

1. "five cards that have ranks that form a contiguous substring of the non-cyclic string A23456789TJK"
2. "five cards that have ranks that form a contiguous substring of the non-cyclic string A23456789TJQK"
3. "five cards that have ranks that form a contiguous substring of the cyclic string A23456789TJK"
4. "five cards that have ranks that form a contiguous substring of the cyclic string A23456789TJQK"
Interpretation 2, but Aces cannot be involved as per the problem statement. Queens can also stand in for any rank.

Problem A. Alaska Don't Release Them
*****
Announcement
Please ignore previous clarifications about the "Double Pacific" hand. "Double Pacific" hands contain two unique pairs of disjoint cards, each pair of which is at the same rank, but the two pairs are at distinct ranks. This is not the same as 4 of a kind.

Problem A. Alaska Don't Release Them
*****
The input specification does not explicitly forbid duplicate cards from appearing in the input.

Are duplicate cards permitted?
For the cards within a hand, we are guaranteed to have distinct cards. However, cards may be repeated across test cases.
