Count down to Christmas with daily programming puzzles 🎄.
I favor code efficiency and readability over code golf and leaderboard (which is too competitive for my current level to gain a foothold 🏋️♂️). Besides, I strive to cover as many edge cases as I can, even the ones that don't appear in the sample input.
Each script reads the corresponding text file in the same folder as input, e.g., day01.py reads input01.txt.
