It’s ambiguous from the description alone which cards are to the left after the deal. The lowest value card has to be moved to the left, but is that the top or bottom of the list as given?
2 1 2 2
1 2 -> 2 1
1 1 1 2
2 2 1 1
or
2 1 2 1 2 1
1 2 -> 2 2 -> 2 2
1 1 1 2 1 1
2 2 1 1 1 2
So I guess this means the values have to increase top to bottom. I’ve edited my first post to correct this, but see you’ve already got it.
