This project requires you to sort a random amount of numbers to be sorted in the right order by using only 2 stacks and with the least amount of movements. The allowed movements were specified:
- sa (swap a): Swap the first 2 elements at the top of stack a.
- sb (swap b): Swap the first 2 elements at the top of stack b.
- ss : sa and sb at the same time.
- pa (push a): Take the first element at the top of b and put it at the top of a.
- pb (push b): Take the first element at the top of a and put it at the top of b.
- ra (rotate a): Shift up all elements of stack a by 1. First becomes last.
- rb (rotate b): Shift up all elements of stack b by 1. First becomes last.
- rr : ra and rb at the same time.
- rra (reverse rotate a): Shift down all elements of stack a by 1. Last becomes first.
- rrb (reverse rotate b): Shift down all elements of stack b by 1. Last becomes first.
- rrr : rra and rrb at the same time.
I've used a simple Algorithm called K-Sort.
(Thanks Azer for showing me such a simple and effective solution - Azer Github-Profile)
