Kattis submission
Submit the IK_functions.py file from the script folder
    containing your solutions.
    Make sure the solution or any files you submit are in
    Python3!
    Use: "#! /usr/bin/env python3" at the top to let Kattis auto
    detect the language.
    Do not submit the entire skeleton! Only the IK_functions.py and
    any additional file you wrote for it.
Kattis Result
Kattis will test your solution on 4 test cases (2 E-level
    and 2 C-level)
- 
        You get 10 Points per E-level Solution (SCARA-Robot) 
- 
        You get 1 Points per C-Level Solution (KUKA-Robot) 
Max score is 22 points.
Grades
E grade for $>=$ 20
    points.
    C grade for $>=$ 22
    points.
