It is really obvious from your memory consumption. It is a stack overflow. Imagine how many recursive calls you will do? Don't you think it is too much? I will give you a hint:
Imagine a stick is $$$X$$$ and a diamond is $$$Y$$$. You will need to minimize the sum of $$$X$$$ and $$$Y$$$ after you simultaneous subtract them. There are two methods of subtraction which will give you an emerald:
$$$X=X-1$$$,$$$Y=Y-2$$$
or
$$$X=X-2$$$,$$$Y=Y-1$$$
thanks
You're welcome!
