Friedman number

Question

I'm trying the Friedman number challenge and I have one problem: how do I generate all possible outcomes with "()"
I'm trying to do it by counting up binary but then I noticed that brackets can be right next to each other
Exempel:
((x + y) *z) ^a

so many combinations... 🤯

Answer 1

one way to do this is to use the reverse polish notation and a stack
