我是铁牌选手

这次比赛非常得爆炸，可以说体验极差，是这辈子自己最脑残的事情之一。

天时，地利，人和一样没有，而且自己早早地就想好了甩锅的套路。

按理说不开K就不会这么惨了啊，而且自己也是毒，不知道段错误也可以是MLE，而且我的内存就是卡了那么一点点，在比赛紧张的状态下人也变傻了吧。

这次的题目难度是两边到中间一次递增的，但是我也不懂榜怎么会那样

Magic Points

Time Limit: 1 Second

Memory Limit: 65536 KB

Special Judge

Given an integer $, we say a point on a 2D plane is a magic point, if and only if both and are integers, and exactly one of the following conditions is satisfied:$

$and;$

$and;$

$and;$

$and .$

It's easy to discover that there are $magic points in total. These magic points are numbered from to in counter-clockwise order starting from .$

DreamGrid can create $magic lines from these magic points. Each magic line passes through exactly two magic points but cannot be parallel to the line or (that is to say, the coordinate axes).$

The intersections of the magic lines are called dream points, and for some reason, DreamGrid would like to make as many dream points as possible. Can you tell him how to create these magic lines?

Input

There are multiple test cases. The first line of input contains an integer $(about 100), indicating the number of test cases. For each test case, there is only one integer ().$

Output

For each case output $integers in one line separated by one space, indicating that in your answer, point and point is connected by a line for all .$

If there are multiple answers, you can print any of them.

Sample Input

Sample Output

0 2 1 31 4 2 5 3 60 6 1 9 3 8 4 10

Hint

The sample test cases are shown as follow:

4n-4个点让你构造直线而且相交点最多，先考虑让他们同方向的，也就是斜率相同的，但是不一定可以构造出来

但是首先要明确的就是按照边走，i连上n+i

最后一条线刚开始直接把对角线的点相连。但是这样有可能会交于同一点，所以是要找最后一点相连还有他的斜率

The protagonist then meets the other members of the club: Natsuki, Yuri, and the club president Monika. The protagonist starts to participate in the club's activities such as writing and sharing poetry, and grows close to the four girls. What a lovely story!

A very important feature of the game is its poetry writing mechanism. The player is given a list of various words to select from that will make up his poem. Each girl in the Literature Club has different word preferences, and will be very happy if the player's poem is full of her favorite words.

The poem writing mini-game (from wikipedia)

BaoBao is a big fan of the game and likes Sayori the most, so he decides to write a poem to please Sayori. A poem of $words is nothing more than a sequence of strings, and the happiness of Sayori after reading the poem is calculated by the formula$

where

is the happiness and is Sayori's preference to the word .

Given a list of $words and Sayori's preference to each word, please help BaoBao select words from the list and finish the poem with these words to maximize the happiness of Sayori.$

Lucky 7

Time Limit: 1 Second

Memory Limit: 65536 KB

BaoBao has just found a positive integer sequence $of length from his left pocket and another positive integer from his right pocket. As number 7 is BaoBao's favorite number, he considers a positive integer lucky if is divisible by 7. He now wants to select an integer from the sequence such that is lucky. Please tell him if it is possible.$

Input

There are multiple test cases. The first line of the input is an integer $(about 100), indicating the number of test cases. For each test case:$

The first line contains two integers $and (), indicating the length of the sequence and the positive integer in BaoBao's right pocket.$

The second line contains $positive integers (), indicating the sequence.$

Output

For each test case output one line. If there exists an integer $such that and is lucky, output "Yes" (without quotes), otherwise output "No" (without quotes).$

Sample Input

43 74 5 63 74 7 65 22 5 2 5 24 26100 1 2 4

Sample Output

NoYesYesYes

Hint

For the first sample test case, as 4 + 7 = 11, 5 + 7 = 12 and 6 + 7 = 13 are all not divisible by 7, the answer is "No".

For the second sample test case, BaoBao can select a 7 from the sequence to get 7 + 7 = 14. As 14 is divisible by 7, the answer is "Yes".

For the third sample test case, BaoBao can select a 5 from the sequence to get 5 + 2 = 7. As 7 is divisible by 7, the answer is "Yes".

For the fourth sample test case, BaoBao can select a 100 from the sequence to get 100 + 26 = 126. As 126 is divisible by 7, the answer is "Yes".

Mahjong Sorting

Time Limit: 1 Second

Memory Limit: 65536 KB

DreamGrid has just found a set of Mahjong with $suited tiles and a White Dragon tile in his pocket. Each suited tile has a suit (Character, Bamboo or Dot) and a rank (ranging from 1 to), and there is exactly one tile of each rank and suit combination.$

Character tiles whose rank ranges from 1 to 9

Bamboo tiles whose rank ranges from 1 to 9

Dot tiles whose rank ranges from 1 to 9

White Dragon tile

As DreamGrid is bored, he decides to play with these tiles. He first selects one of the $suited tiles as the "lucky tile", then he picks tiles from the set of tiles and sorts these tiles with the following rules:$

The "lucky tile", if contained in the $tiles, must be placed in the leftmost position.$

For two tiles $and such that neither of them is the "lucky tile", if$
- $is a Character tile and is a Bamboo tile, or$
- $is a Character tile and is a Dot tile, or$
- $is a Bamboo tile and is a Dot tile, or$
- $and have the same suit and the rank of is smaller than the rank of,$
then $must be placed to the left of .$

White Dragon tile is a special tile. If it's contained in the $tiles, it's considered as the original (not-lucky) version of the lucky tile during the sorting. For example, consider the following sorted tiles, where "3 Character" is selected as the lucky tile. White Dragon tile, in this case, is considered to be the original not-lucky version of "3 Character" and should be placed between "2 Character" and "4 Character".$

As DreamGrid is quite forgetful, he immediately forgets what the lucky tile is after the sorting! Given $sorted tiles, please tell DreamGrid the number of possible lucky tiles.$

Input

There are multiple test cases. The first line of the input contains an integer $, indicating the number of test cases. For each test case:$

The first line contains two integers $and (,), indicating the number of sorted tiles and the maximum rank of suited tiles.$

For the next $lines, the -th line describes the -th sorted tile counting from left to right. The line begins with a capital letter (), indicating the suit of the -th tile:$

If $, then an integer () follows, indicating that it's a Character tile with rank;$

If $, then an integer () follows, indicating that it's a Bamboo tile with rank;$

If $, then an integer () follows, indicating that it's a Dot tile with rank;$

If $, then it's a White Drangon tile.$

It's guaranteed that there exists at least one possible lucky tile, and the sum of $in all test cases doesn't exceed .$

Output

For each test case output one line containing one integer, indicating the number of possible lucky tiles.

Sample Input

43 9C 2WC 46 9C 2C 7WB 3B 4D 23 100C 2WC 93 9C 1B 2D 3

Sample Output

Hint

For the first sample, "2 Character" and "3 Character" are possible lucky tiles.

For the second sample, "8 Character", "9 Character", "1 Bamboo" and "2 Bamboo" are possible lucky tiles.

Sequence Swapping

Time Limit: 1 Second

Memory Limit: 65536 KB

BaoBao has just found a strange sequence {< $, >, <, >,, <, >} of length in his pocket. As you can see, each element <, > in the sequence is an ordered pair, where the first element in the pair is the left parenthesis '(' or the right parenthesis ')', and the second element in the pair is an integer.$

As BaoBao is bored, he decides to play with the sequence. At the beginning, BaoBao's score is set to 0. Each time BaoBao can select an integer $, swap the -th element and the -th element in the sequence, and increase his score by, if and only if,'(' and')'.$

BaoBao is allowed to perform the swapping any number of times (including zero times). What's the maximum possible score BaoBao can get?

Input

There are multiple test cases. The first line of the input contains an integer $, indicating the number of test cases. For each test case:$

The first line contains an integer $(), indicating the length of the sequence.$

The second line contains a string $() consisting of '(' and ')'. The -th character in the string indicates, of which the meaning is described above.$

The third line contains $integers (). Their meanings are described above.$

Magic 12 Months

Time Limit: 1 Second

Memory Limit: 65536 KB

It's New Year's Eve, and it's also the best time of the year to play the card game Magic 12 Months to pray for good luck of the coming year. BaoBao has just found a deck of standard 52 playing cards (without Jokers) in his pocket and decides to play the game. The rules are as follows:

Setup
1. Remove the four 'K's from the 52 cards.
2. Shuffle the remaining 48 cards and divide them face down into 12 piles (4 cards per pile) with equal probability.

Gameplay
1. Let $.$
2. Flip the card on the top of the $-th pile, check its rank, and discard the card.$
3. If $is a number, let; If, let; If, let; If, let .$
4. If the $-th pile is empty, the game ends; Otherwise go back to step 2.2.$

When the game ends, having all the 4 cards of rank $flipped and discarded indicates that the -th month in the coming year is a lucky month.$

BaoBao is in the middle of the game and has discarded $cards. He wants to know the probability that the -th month of the coming year is a lucky month for all when the game ends. Given these cards, please help him calculate the answer.$

Input

There are multiple test cases. The first line of input contains an integer $(about 100) -- the number of test cases. For each test case:$

The first and only line contains an integer $() -- the number of flipped cards, followed by the rank of the cards () separated by a space in the order they are flipped. It's guaranteed that the input describes a valid and possible situation of the game.$

Output

For each test case output one line containing 12 numbers separated by a space, where the $-th number indicates the probability that the -th month of the coming year is a lucky month.$

You should output a probability in its simplest fraction form $where and are coprime. Specifically, if the probability equals 0, you should output 0; If the probability equals 1, you should output 1.$

Please, DO NOT output extra spaces at the end of each line, or your answer may be considered incorrect!

Sample Input

330 9 Q 10 J Q 10 J 10 J J 8 5 7 6 5 7 6 7 6 6 3 A 2 4 A 2 4 2 4 407 2 A 3 A 4 A A

Sample Output

1 2/3 2/5 1 1/2 1 2/3 2/5 2/5 2/3 1 1/21 1/2 1/2 1/2 1/2 1/2 1/2 1/2 1/2 1/2 1/2 1/21 0 0 0 0 0 0 0 0 0 0 0
