Day 378

[vaskoz]

Good morning! Here's your coding interview problem for today.

This problem was asked by Coinbase.

Write a function that takes in a number, string, list, or dictionary and returns its JSON encoding. It should also handle nulls.

For example, given the following input:

[None, 123, ["a", "b"], {"c":"d"}]

You should return the following, as a string:

'[null, 123, ["a", "b"], {"c": "d"}]'
