Solutions to LeetCode problems in Python.

Adding a new problem

python add.py <problem_number>

This will:

• Fetch the problem title, difficulty, and link from LeetCode
• Generate a file in main/ with the solution stub and example test cases pre-filled
• Print an error if the problem already exists or requires a Premium subscription

Example:

python add.py 53
# Created: main/0053_maximum_subarray.py  [Medium]

Once the file is created, fill in your solution. The expected outputs in each assert are already filled in.
