This is a parser - buildtool for codeforces.
- 
Inbuilt parser that scrapes input and output test-cases of all questions of a particular contest.    
- 
code can be compiled and tested against all provided input test-cases (scraped) to check for correctness. This is shown in Output.txt  
- 
Provide custom input test cases. 
- 
Clone this repo. 
- 
Open this folder as work-space in VS Code. ( code .in terminal)
- 
Make necessary changes to template.cpp ( present inside .vscode ). This acts as your default .cpp file for all problems of a contest. 
- 
Now, use the keybinding ctrl+shift+b, and select Create Files.
- 
Use ctrl+shift+`to open integrated terminal in vs code. Here type in./parse.py (contest_name)(eg../parse.py 4) to download all the test-cases (input and output) of that particular contest.
- 
To open codespace for question A, using the keybindings ctrl+pand type in A.cpp
- 
To open Output.txt by using the keybindings ctrl+pand type Output.txt
- 
To build and test-run code on given test-cases, use ctrl+shift+band select codeforces builder.
- 
Custom test-cases can be provided on Input.txt. Follow step 7 and instead of Output.txt, search for Input.txt 
Special thanks to johnathan79717 for the parser.
