Array Duplicate Finder Complexity | Dataford Interview Questions

Write a simple function to find duplicates in an array. What are the time and space complexities?

Implement find_duplicates(nums). Given a list of integers, return each value that appears at least twice exactly once, ordered by the position where its duplicate occurrence is first detected. Return an empty list when there are no duplicates.

Function signature: def find_duplicates(nums): Input is a list of integers, and output is a list of integers.

Constraints

0 <= nums.length <= 1000
-10^9 <= nums[i] <= 10^9
Each duplicated value appears once in the output
Output order follows the first detected duplicate occurrence

Function Signature

def find_duplicates(nums):
