HackerrankIt

Command line tool to initialize a small project directory to solve a problem.

1. C++

Assume you already have Ruby installed in your environment.

gem install hackerrankit

hackerrankit will treat your current working directory as the root point to create separated directory for each problem you are going to solve.

hackerrankit [url] [language]

where:

[url] is the url to the problem on Hackerrank.

language is the language you are going to solve the problem. To keep this gem simple, I don't consider the situation where you want to solve a problem with more than one language. Default: C++.

After you issue hackerrankit, it does the following steps:

1. Silently go to the url to extract information about that problem such as name, sample input, sample output.
2. Base on the name, it creates a directory inside your current working directory whose name equals to the problem's name replaced spaces with - character. Example: ACM ICPC Team -> acm-icpc-team.
3. Base on the language you specified in the command, it creates minimal necessary files for you to start working on the problem right a way. For example, with C++, it creates main.cpp, sample.input, sample.out, and run.sh for you to compile your solution, run it with sample.input and compare to sample.output. Its output is either Accepted or Wrong Answer.
4. hackerrankit will try its best to initialize your main.cpp with useful declarations so you don't need to worry about them everytime you want to practising problem solving. For example: with C++, it will have common includes and useful #define, main function.

This is firstly my gem to make my problem solving practising less time consuming so I will only focus on the language that I use. Currently is C++.

If you want to support your preferred language such as Ruby, Python, Java, C, Pascal whatever. Feel free to folk and make a PR. Or you just want to make it for yourself, feel free to copy the tool. Even nicer if you can give this repository a star which would definitely make my day.
