We recommend writing answers in whatever language you’re most comfortable in. Like our own code, we expect testing instructions: whether it’s an automated test framework, or simple manual steps.
To help set expectations, we believe this should take under 3-4 hours to complete. We understand that you have other responsibilities, so if you think you’ll need more than 3-4 days, just let us know when you expect to send a reply.
You might find gist.github.com a convenient way to send us your work.
Write some code that will flatten an array of arbitrarily nested arrays of values into a flat array of values. For example, flattener([[1,2,[3]],4]) would return [1,2,3,4].
Automated tests that illustrate how ensure the correctness of your solution are ideal, but if you don't include them, give us a decent writeup and some of the input cases you used.
Here are a few test cases to make sure you have the right idea:
input: [[1,2,3],4], output: [1,2,3,4]
input: [[1,2,[3]],4], output: [1,2,3,4]
input: [[1,[[2]],[3]],4], output: [1,2,3,4]
Many Nutshell components communicate with web servers for their data. Here you’ll interact with a REST API that returns information about people. This API is paginated, so you’ll need to make multiple requests to gather all people.
The URL endpoints look like:
- http://join.nutshell.com/people/1/
- http://join.nutshell.com/people/2/
- http://join.nutshell.com/people/3/
- (... etc.)
When you go beyond the number of full pages, you’ll receive an empty array.
Each page looks like this:
[
{"name": "Andy Fowler", "email": null, "signup_date": "2017-01-03"},
{"name": "Andrew Sardone", "email": "[email protected]", "signup_date": "2017-01-02"},
[ ... and many others ...]
]
Write some code that prints the 5 newest people (by signup date) that have a non-null email address.
