Daily Coding Problem: Problem #173 [Easy]

Good morning!

Here's a solution to yesterday's problem.

This is your coding interview problem for today.

This problem was asked by Stripe.

Write a function to flatten a nested dictionary. Namespace the keys with a period.

For example, given the following dictionary:

{
    "key": 3,
    "foo": {
        "a": 5,
        "bar": {
            "baz": 8
        }
    }
}

it should become:

{
    "key": 3,
    "foo.a": 5,
    "foo.bar.baz": 8
}

You can assume keys do not contain dots in them, i.e. no clobbering will occur.

We will be sending the solution tomorrow, along with tomorrow's question. As always, feel free to shoot us an email if there's anything we can help with.

Have a great day!
