This python script was created to visualize your work with the PUSH_SWAP
42 Project.
You must put this script in the same path or in a sibling path of your program
Of course you need Python3 with the builtin Tkinter.
You can install it with Brew.
--> Brew install python3
Execute the script with :
--> python3 pyviz.py `ruby -e "puts (-200..200).to_a.shuffle.join(' ')"`
You can change the PUSHS_PATH to get to the relative path of your push_swap
You can decrease or increase the speed with the matching buttons.
