This is a repository of my solutions to practice LeetCode problems in Python3. Each solution is in its own file. If my solution differs significantly from the reported solution, then that solution is added to the bottom of the .py file and identified as different from my solution via comments in the .py file.
.py files with the prefix z_ are files that I used to try to understand the inner workings of an agorithm or data structure that was applied to a problem. The applicable problem number is in a parenthetical at the end of the file name (e.g., _(2)).
Problems with which I had trouble or that I would like to review at a later date are marked with a starting hyphen.
