Rooted.
Thnx @avonsec and @mty0x . It seemed difficult initially because I did not know the python language very well. However, I realized later that it was very easy.
User: Read sss.py and find vulnerability. Then find and read the other files. Understand the logic. if 5+key=10, 10-5=key
Root: Very easy. You will use a known technique. Read the relevant file and understand how it works.
PM me for hint
