README

Codeforces Helper

npm version

Codeforces Helper is a Node.js executable that accepts a URL to a problem or contest in www.codeforces.com, and sets up a folder for the problem with all the test cases. As a bonus, a template and test script is made! This saves a lot of setup time, so one can just focus on solving the problem! :smile:

NOTE: To use the test script, the C++ executable should be named "sol" (g++ -std=c++14 <code.cpp> -o sol)

Codeforces Helper is free to use! If you like it, please support me and give it a star on my Github, www.github.com/callistusystan/codeforcesHelper :star:

If there are any problems with the tool, feel free to raise an issue on the Github repo, www.github.com/callistusystan/codeforcesHelper/issues or send me an email at callistusystan@gmail.com

Announcements

While Codeforces Helper is still working fine, I would like to introduce my newer and improved tool, Codr. Codr has a simpler API, and is designed the way I should have done when implementing cfhelper.

Codr's goal is to be able to parse problems from more coding platforms, which is possible with its extensible design.
