1 issue in s15q02_solution.py, I was not able to test the function, it was always showing successful because once the list sorted even the copy of lists were also changed original list was lost in all cases. My sorting is working as sort(), but copy of a list is also pointing to the same memory and changed. Can be seen by un-commenting the commented statements in the function.
