Duplicate Integers in an Array | Dataford Interview Questions

Write a method to print duplicate integers in an array of integers.

Implement print_duplicates(nums), which returns a list containing each duplicated value exactly once, ordered by the index where it is first identified as a duplicate. The input is a list of integers, and the result should be an empty list when no value occurs more than once.

Constraints

0 <= nums.length <= 1000
-10^9 <= nums[i] <= 10^9
Return each duplicated integer exactly once
Preserve the order in which duplicates are first identified

Function Signature

def print_duplicates(nums):
