Catalyst
Catalyst is a VS code Extension to accelerate the process of solving problems on Codeforces. It automatically fetches the problem and displays it, parses test cases, runs and evaluates your code on test cases. You can edit/add/remove test cases as you like, and when you are done, it can submit your code and then track the submission in realtime.
Quick Start
- Open any folder in VS code.
- Press
Ctrl + Alt + Por use command Add Problem/Contest from command palette. - Enter problem/contest URL from Codeforces and then select a language
After this VS code layout will split into 2 columns, in the left column there will be source code and in the right column, the problem will be displayed with preloaded test cases. In which you can run, evaluate, and submit your code.
