Nested Dict Access

Given nested dict and list of keys, return value. Example: {"a":{"b":5}}, ["a","b"] => 5

Your task

Implement this function:

def nested_dict_access(d: dict, keys: list):

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: d, keys.

Example

Input

{'a': {'b': 5}}
['a', 'b']

Output

5
