One of the great coding exercises I enjoyed solving was the 0-1 sequences problem from Kattis. My (2018 or 2019) python solution could not be fast enough if I did not write the problem mathematically.

As usual, "it is not just about writing a code that works, but rather one that efficiently does so."

PS: Although I am among the 1633 accepted authors (over 14914 submissions in August 2022), my solution is not among the ten best python solutions.

I am trying to use my github account more often now...
