Description

After the shameful loss in the match against Jesus Quintana, The Dude, Donny and Walter decided to turn to poker and become rounders. First of all, they decided to learn to deal with cards.

Walter gave Donny a simple task—he should split a deck of 52 cards into four piles in such a way that cards in each pile would be sorted in the order of ascending value. Two should be the topmost card, three should be the next card and so on. Ace should lie in the bottom. Walter wanted all decks to be comprised of the cards of the same suit but he forgot to mention it. As a result, the suits in piles were shuffled.

The Dude decided to save the day. But after five White Russians he poured into himself yesterday he isn't in a good condition for thinking. In fact, he is able to perform only the following actions:

• take a few cards of one suit from the top of a deck and create a new deck of them;
• take a few cards of one suit from the top of a deck and put them onto a card which value is greater by one than the value of the bottommost of the taken cards.

The Dude doesn't change the order of cards while moving them.

Help The Dude to complete Walter's task before Walter get insane and shoot both his best friends with Uzi.

 

Input

The input consists of four lines describing the piles of cards. Each line contains the description of 13 cards in a pile in order from top to bottom (that is, in the order of ascending values). Each card is denoted by its value and its suit. The value is one of the following: 2, 3, …, 9, T (ten), J (jack), Q (queen), K (king), A (ace), the suit can be: S (spades), C (clubs), D (diamonds) or H (hearts). All cards in the input are different.

Output

Output the minimal number of operations The Dude should perform in order to obtain four piles consisting of cards with the same suit.

题意

其实就是蜘蛛纸牌啦

一开始给你4个正确序列的纸牌

然后每次你就只能从上面拿下来一堆

然后问你最少几次操作可以得到上面的序列

题解：

我们对于每一行判断就好了，如果这一行有两个区别的话，那就加3啦，如果有3个区别，就加4，如果有4个区别，那就有两种，特判一下就好了
