Two Piles, One Kitchen

Two dish piles: one for plates, one for pans — commands come with an address. 🍳

You get commands like a:add:fork, b:add:pot, a:take, b:take (takes valid). Print pile A on line one and pile B on line two (bottom to top, comma-separated, or empty).

Example:

Input: commands = ["a:add:fork", "b:add:pot", "a:add:cup", "a:take"] Output:

fork
pot

Pile A gets fork then cup; a:take removes cup, leaving just fork. Pile B just has pot.
