This repo is created for daily challenges of LeetCode, starting from April 1, 2023, mostly with python3.

IMPORTANT NOTICE: some codes are gathered from internet and not all of them are not my original work.

Getting Questions

First, install requirements:

pip install -r requirements.txt -U 

To get any question, with problem and description, use download command.

python main.py -d True 

and to get any other, use:

python main.py -s `QUESTION_SLUG`

QUESTION_SLUG can be extracted from any problem url, which looks like this:

https://leetcode.com/problems/{QUESTION_SLUG}/

Running Locally

Most questions consist of a class Solution, and a mainMethod(**kwargs) that needs to be implemented. To be able to run this file, simply create a python file with this schema:

from testing.solution_test import BaseSolutionTest


class Solution:
    def __init__(self):
        self.main = self.mainMethod

    def mainMethod(self, **kwargs):


BaseSolutionTest(Solution, )

To twick your tests a little, you can create BaseSolutionTest with optional inputs. example_file is obvious, but to use specific tests, define them by providing a list, with relevant IDs (i.e [1,3]).

BaseSolutionTest(self, solution_class, example_files: str = "test_cases.json", used_tests:List = None):

This file will be added automatically if you use download command.

You can add your own test cases, by simply adding to {DIFFICULTY}/{QUESTION_ID}/test_cases.json, just use the correct schema:

{
  "TEST_NAME": {
    "input": {
      "FIRST_INPUT_NAME": "VALUE"
    },
    "output": "OUTPUT_VALUE"
  }
}
