I’ve completed this lesson and I’ve saved it:
https://www.codecademy.com/courses/sorting-algorithms/lessons/radix-sort-python/exercises/finding-max-exponent
After a few minutes after this lesson(I did the a quiz after), the whole lesson went back to the start but the code saved. This is the first time this happened on my Codecademy courses. Can you explain why this such strange thing happened.
