CP Scripts

I am trying to learn bash scripting and the same time try to use it for the purpose of speeding up my competitive programming experience. For that I will be creating several scripts. For now its only cf_run script which runs sample test cases taken from problem page on Codeforces and run it against your program output file and tells how many of the sample test cases passed.

I am newbie at bash scripting, so I apparently was not able to catch all the errors and also the code might consist of some extra useless code.

Script	Function
cf_run	Runs the sample test cases and shows the status of output for Codeforces contests

Usage

The scripts have been tested for Ubuntu 20.04 (If the script works on your device as well, feel free to add it here!). You can follow this given steps to get the things working.

1. Clone this repository using git clone command.
2. Make sure all the scripts are executable, if not you can make them executable using chmod +x script-name command.
3. Add this directory to your PATH, so that you can use it from anywhere.
4. Follow the respective steps for each directory.

cf_run

This script will run you program against the sample test cases present on problem page on Codeforces, so the name cf_run. For this to work you need to make sure following things -

• You need to create a directory for the contest you are participating in. Let's say you are participating in contest 1619, then you have to create a directory with the same name, you can use this command mkdir 1619 && cd 1619.
• Let's say for problem statement A, you create a file called a.cpp and compile it. Let's say compiled file has a name a.out.
• Then to run your file, you will use the command cf_run a.out A, which basically runs sample test cases for problem statement A against a.out file.

Working: It takes contest_id from the name of your directory (here 1619), then using this id and second argument of the command (i.e. problem_code, here A), it scrapes the webpage https://codeforces.com/contest/1619/problem/A.
