Setup

Requirements

Git, Node v4.0.0 or higher and NPM

Environment

1. Clone repo with git

   git clone https://github.com/csvn/kattis.runner.git
   

2. Install npm packages

   npm install
   

3. Run node, optionally with gulp

   gulp run
   

4. Profit! (but probably not...)

Gulp

There are 3 gulp tasks:

• default - The other tasks will be executed
• run - Will run solution once
• watch - Watches files and calls run on changes

Solution

solution.js

Write all your solution code in solution/solution.js. When you have your gulp task up and running, a file that can be submitted directly to kattis will be generated and placed in solution/submission.js.

io-sets.js

solution/io-sets.js contains groups of inputs, and groups of expected output to check your solution against. Set output to a non-string to not compare the result with the expected output.

Tips

• Use default gulp task, and submit submission.js when you're satisfied

Notes

Kattis uses a SpiderMonkey engine version (C24.2.0) that is roughly the version that was used in browser Firefox v24. This means that care needs to be taken when using e.g. array methods which may not be present in the engine.
