algorithm to sort numbers with push_swap instructions.
You have at your disposal a set of integer values, 2 stacks (A and B), and a set of instructions to manipulate both stacks.
the push_swap program made calculates and displays on the standard output the smallest program, made of Push swap language instructions, that sorts the integers received as arguments.
• You have 2 stacks named a and b.
• At the beginning: ◦ The stack a contains a random amount of negative and/or positive numbers which cannot be duplicated. ◦ The stack b is empty.
• The goal is to sort in ascending order numbers into stack a. To do so you have the following operations at your disposal:
sa (swap a): Swap the first 2 elements at the top of stack a. Do nothing if there is only one or no elements.
sb (swap b): Swap the first 2 elements at the top of stack b. Do nothing if there is only one or no elements.
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. Do nothing if b is empty.
pb (push b): Take the first element at the top of a and put it at the top of b. Do nothing if a is empty.
ra (rotate a): Shift up all elements of stack a by 1. The first element becomes the last one.
rb (rotate b): Shift up all elements of stack b by 1. The first element becomes the last one.
rr : ra and rb at the same time.
rra (reverse rotate a): Shift down all elements of stack a by 1. The last element becomes the first one.
rrb (reverse rotate b): Shift down all elements of stack b by 1. The last element becomes the first one.
rrr : rra and rrb at the same time.
progaram named checker created to check whether the list of instructions generated by the push_swap program actually sorts the stack properly.
to compile all the medatory functions into object files then archive them to a push_swap progarmuse the command:
make
or you can use:
make all
for the bonus part use:
make bonus
to delete the object files you can use:
make clean
and to the delete the object files and the program you can use:
make fclean
rebuilding the library will be done if you use:
make re
