Flatten Nested Lists | Dataford Interview Questions

How would you convert a nested list that contains either nested lists or integers into a single flat list?

Implement flatten_nested_list(nested). The input is a list whose elements are integers or lists with the same structure. Return a new list containing all integers in left-to-right order.

Constraints

0 <= number of integers and nested lists <= 10^4
Nesting depth is at most 500
-10^9 <= each integer <= 10^9
Every element is either an integer or a list

Function Signature

def flatten_nested_list(nested):
