3sum leetcode python.
There is apparently a bug in my code that I couldn't figure out, even after running the Python Debugger. My code gives the wrong result when I use the input of [-11, 1, -12, -12, 10]. It creates an unnecessary duplicate in the answer. I've never seen this happen before, but Python seems to run the for loop one too many times.
