If you've ever been to China, you may have noticed that local people, especially the elderly, like to play a special game called MahJong, and sometimes people bet on it.

When the game starts, people are supposed to take turns rearranging their "cards" (in fact, they look like tiles rather than cards), and if one's tiles fit the winning pattern, then one wins, or "hoos" (胡了, hú le ).

Tiles

There are 34 kinds of tiles in total:.

English:

1 million, 2 million, 3 million, ... 9 million

sparrow,   2 worms,   3 worms,   ... 9 worms  (also bamboo)

1 pancake,   2 pancakes,   3 pancakes,   ... 9 pancakes  (also circle)

Cardinal tiles : east,   south,   west,  north

Honor tiles:middle,   rich,   blank.

Chinese:

1万，2万，3万，... 9万

鸟，2条，3条， ... 9条 (也叫索)

1饼，2饼，3饼，... 9饼 (也叫筒)

东 西 南 北 中 发 白

Groups:

Straight, 顺子: Three of the continous tiles.

Triplet, 刻子: three of the same tiles

Pair, 眼: two of the same tiles

Task:

write a function, check if certain pattern fits winning pattern.

A winning pattern should have 14 tiles.

normal winning pattern :

the number of triplets and the number of straight should add up to FOUR, and remaining two tiles should be a pair.

examples:

unusual winning pattern - seven pairs,  七对子

example:

unusual winning pattern - independence,  全不靠

Each tile is belong to   {east，south，west，north，middle，rich， blank} and   (1，4，7)(million)， (2，5，8)(pancakes), (3,6,9)(worm)
THE MILLION，PANCAKES，AND WORM IN PARENTHESES ABOVE ARE INTERCHANGABLE!
example:

unusual winning pattern - thirteen orphans,  十三幺

east，south，north，west，middle，rich，blank，1 million，9 million，1 pancakes，9 pancakes，sparrow，9 worms，random tiles above.
example:

The function receives a string and returns a boolean, to check if the tiles fit the winning pattern.

All test points will be in Chinese. If you think Chinese chracters are difficult to type, I preload some characters for you.
