Ninja is in space with his super spaceship having unlimited fuel. Ninja initially has a health level ‘H’ and his spaceship has an armour ‘A’. He decides to play a game, where at any instant he can be only on one of the 3 planets: VENUS, MARS or SATURN. At every unit of time, he has to change his location and you can assume he can change his location instantly. Each planet has different effects on health and armour which are :
Venus: Decreases health by 4, decreases armour by 8.
Mars: Increases health by 3, increases armour by 2.
Saturn: Decreases health by 10, increases armour by 5.
Now the game will end if either ‘H’ <= 0 or ‘A’ <= 0.
Your task is to find the maximum time Ninja can survive.
Note :
You can choose any of the 3 planets during your first move.
