# --description--
|
|
|
|
Given a trick name consisting of two words, determine if it is a valid freestyle skiing trick name.
|
|
|
|
A trick is valid if the first word is in the list of valid first words, and the second word is in the list of valid second words.
|
|
|
|
- The two words will be separated by a single space.
|
|
|
|
Valid first words:
|
|
|
|
|`"Misty"`|
|
|
|-|
|
|
|`"Ghost"`|
|
|
|`"Thunder"`|
|
|
|`"Solar"`|
|
|
|`"Sky"`|
|
|
|`"Phantom"`|
|
|
|`"Frozen"`|
|
|
|`"Polar"`|
|
|
|
|
Valid second words:
|
|
|
|
|`"Twister"`|
|
|
|-|
|
|
|`"Icequake"`|
|
|
|`"Avalanche"`|
|
|
|`"Vortex"`|
|
|
|`"Snowstorm"`|
|
|
|`"Frostbite"`|
|
|
|`"Blizzard"`|
|
|
|`"Shadow"`|
|
|
|
