Zipmap

Within Doc2Doc we need to map certain properties from one document to properties of another document. Complete the recursive zipmap function.

It takes two lists as input and returns a dictionary where the first list provides the keys and the second list provides the values.

Example usage:

zipped: dict[str, float] = zipmap(
    [
        "Avatar: The Last Airbender",
        "Avatar (in Papyrus font)",
        "The Last Airbender (Live Action)",
    ],
    [9.9, 6.1, 2.1],
)

print(zipped)
# {
#   'Avatar: The Last Airbender': 9.9,
#   'Avatar (in Papyrus font)': 6.1,
#   'The Last Airbender (Live Action)': 2.1,
# }

Here's the pseudocode:

1. If either the keys or the values list is empty, return an empty dictionary (base case). This takes care of creating a dictionary.
2. Recursively call zipmap on all but the first elements from keys and values.
3. Add the first element of keys to the resulting dictionary, and set its value to the first element in values.
4. Return the updated dictionary.
