Enum StackOp 

pub enum StackOp {
    Push(Arg),
    Pop(Arg),
}

Each integer being parsed consists of 18 lines of very similar code. We’ll cheat and only represent it with the pieces that are different.

Part of this instruction stream is implementing push/pop via an integer and multiplication/division, and we only care about one piece of data in each case.

Variants

Push(Arg)

Pop(Arg)
