This is my approach to the amazon india travelling code ninja programming challange. Just for fun, the code is written in plain vanilla javascript which is not actually part of the test.
You may want to take the challange yourself here and if you'll make it, you may want to apply at Amazon. Or, if you are more keen on working in Berlin/Germany… maybe you want to apply for my team @ ZEIT ONLINE. Feel free to contact me on Twitter or here on github.
Best case would certainly be, you fork this code and make better (even also just for fun).
