If you have participated in NOIP 2015 and PKUWC 2018, you must have a deep impression of a problem called "Landlords". To pay tribute to the classics, we have created another problem about playing cards. In this problem, the card types are similar but not identical to those in Landlords; we call the poker game in this problem "Master Landlords".
Master Landlords is a poker game played with a standard 54-card deck (A through K of spades, hearts, clubs, and diamonds, plus the small joker and big joker). There is one of each joker, and four of each other rank. In Master Landlords, the rank of the cards is as follows: $3 < 4 < 5 < 6 < 7 < 8 < 9 < 10(T) < J < Q < K < A < 2 <$ small joker $(w) <$ big joker $(W)$. Suits do not affect the rank of the cards. Each game consists of a hand of $n$ cards. Players can play cards according to specified patterns, and the first player to empty their hand wins. To simplify the problem, we ignore suits, meaning all cards of the same rank are considered identical.
In this problem, the allowed card patterns are (note that this part differs from traditional Landlords):
| Name | Explanation | Example | Note |
|---|---|---|---|
| Single | A single card | 6 | A single joker is also a single |
| Pair | Two cards of the same rank | 66 | Jokers do not form a pair |
| Three-of-a-kind | Three cards of the same rank | 666 | |
| Three-with-one | Three cards of the same rank plus one single card | 666w | |
| Three-with-two | Three cards of the same rank plus a pair of a different rank | 66699 | |
| Straight | 5 or more single cards of consecutive ranks | 3456789 | Cannot contain jokers or 2 |
| Consecutive pairs | 3 or more pairs of consecutive ranks | 33445566 | Cannot contain jokers or 2 |
| Consecutive threes | 2 or more sets of three-of-a-kind of consecutive ranks | 333444555 | Cannot contain jokers or 2 |
| Four-with-two | Four cards of the same rank plus two single cards | 444456 444455 | Cannot contain two pairs |
| Airplane (single wings) | Consecutive threes with the same number of distinct-rank single cards | 33344455569J | |
| Airplane (double wings) | Consecutive threes with the same number of distinct-rank pairs | 3334446699 |
Note:
- There is no "consecutive bomb" pattern, but a sequence like 444455556666 can still be played; it is treated as a 444555666 airplane (single wings) with 456 as the wings.
- The big joker and small joker have different ranks, so an airplane with jokers is legal, e.g., 333444wW.
- It is easy to verify that the rules for the above patterns are valid, meaning any legal set of cards has a unique pattern.
- There are no bombs in the allowed patterns. Bombs are treated as "three-with-one" and have no special effect; they cannot beat any other pattern.
- There are no rockets. This means wW is no longer a legal pattern.
Two hands belong to the same pattern if and only if they have the same name and contain the same number of cards. There is a ranking between hands of the same pattern:
- The rank of "three-with-one" and "three-with-two" depends on the rank of the three cards.
- The rank of an airplane depends on the rank of the consecutive threes.
- The rank of "four-with-two" depends on the rank of the four cards.
- The rank of other patterns depends on the highest-ranking card in the set.
The game process of Master Landlords is described as follows:
- There are two players in the same camp who must work together to achieve the goal. For convenience, we assume the first player is Kaguya and the second player is XX-Netizen.
- The game uses one complete deck of cards. At the start of the game, all 3s are removed. Then, both players are dealt 17 cards randomly from the remaining deck, and the remaining 16 cards are discarded. You can assume that after shuffling, Kaguya takes the first 17 cards, XX-Netizen takes the next 17, and the remaining 16 are discarded.
- The game consists of several rounds, each with two steps:
- Step 1: Kaguya chooses any pattern of any rank from her current hand and plays it ($C$).
- Step 2: XX-Netizen chooses a card $C'$ from his hand that has the same pattern as $C$ and a strictly higher rank. If no such card exists, the game is lost.
- After a round, if at least one of Kaguya or XX-Netizen has no cards left, the game ends. If both players have no cards left, they win; otherwise, they lose.
Here is an example:
Suppose Kaguya's hand is 44445556789TJQKwW and XX-Netizen's hand is 666789TJQKAAAA222. A winning strategy is:
- Round 1: Kaguya plays 4444wW, XX-Netizen plays AAAA22.
- Round 2: Kaguya plays 6789TJQ, XX-Netizen plays 789TJQK.
- Round 3: Kaguya plays 555K, XX-Netizen plays 6662.
This game tests the tacit understanding between the two players. However, since Kaguya and XX-Netizen cannot communicate, they decide to play with their cards revealed, meaning both know the other's hand. Since both play optimally, the outcome is determined as soon as the cards are dealt.
Given XX-Netizen's hand, you need to calculate how many different possible hands Kaguya could have that would result in a win.
Note: Both XX-Netizen's and Kaguya's cards come from the same deck, and 3s are removed before dealing.
Input
Each input consists of a single line containing a string of length 17 representing XX-Netizen's hand. We use 456789TJQKA2wW to represent each card rank.
Output
For each input, output an integer representing the answer: the number of possible hands for Kaguya that result in a win. The answer may be large, so output it modulo 998244353.
Note: We do not consider suits in this problem. If two hands have the same composition of ranks, they are considered the same, even if the suits differ.
