I did not code a solution and only read what's on that page, didn't log in.

It does not matter in which order buttons are pressed.

It does not make sense to press the same button twice, as the second press only reverts what the first did.

Potential solution to the problem can be mapped to subsets of buttons.

Generate all subsets of buttons, ordered by number of elements in that subset.
