Fetches a random problem from https://codeforces.com, creates a markdown description, input and output files, a python solution template, create unit tests and saves all of them on a brand new directory.
Why do I need this? - To easily get new problems to solve without leaving the IDE and switchig to the browser. All the information necessary is saved in the same place.
How does it works? The script uses the official api to to select a new problem within a rank range and then scraps the page of the problem, process a little the html to make it more readable on markdown and create the new files.
- Problem description integrated to the code (no more pasting in the comments).
- Automatic input and expected output files (no more copying and pasting data from the examples).
- Automatic solution template code (no more recriating the same template solution for every new problem).
- Efficiently finds and download new problems directly from the IDE.
- Automatically creates unit tests from the problem examples, testing both the correctness of the anser and the elapsed time constraint.
git clone https://github.com/edkb/CodeForcesScrapper
pip install requirements.txt
python get_problem.py
New problem on ./Name_of_the_Problem
cd /Name_of_the_Problem
New directory with the folowing template:
├── Name_of_the_Problem
│ ├── __init__.py
│ ├── Name_of_the_Problem.md
│ ├── expected_output.txt
│ ├── input.txt
│ ├── output_solution.txt
│ ├── solution.py
│ └── test_solution.py
Read the problem from the Name_of_the_Problem.md.
Code your solution on the solution.py file.
Run your solution like this:
python solution.py < input.txt > solution_output.txt
Here you can compare if the output from your code in solution_output.txt is equal to the expected_solution.txt content.
If everything is fine, test your code like this:
pytest test_solution.py
If it pass all the tests, you're ready to submit the problem.
Happy coding!
