 John learns to play poker with his uncle. His uncle told him: Poker to be in accordance with the order of "2 3 4 5 6 7 8 9 10 J Q K A". The same suit should be put together. But his uncle did not tell him the order of the four suits. 
 
 Give you John's cards and Uncle's cards(two string `john` and `uncle`). Please reference to the order of Uncle's cards, sorting John's cards. 
 
 
# Examples

```
For Python:

Suits are defined as S, D, H, C.

sort_poker("D6H2S3D5SJCQSKC7D2C5H5H10SA","S2S3S5HJHQHKC8C9C10D4D5D6D7")
should return "S3SJSKSAH2H5H10C5C7CQD2D5D6"
sort_poke("D6H2S3D5SJCQSKC7D2C5H5H10SA","C8C9C10D4D5D6D7S2S3S5HJHQHK") 
should return "C5C7CQD2D5D6S3SJSKSAH2H5H10" 

wtf does this mean?
