____summary ____
function's logic is straightforward and efficient:

It creates a map (similar to a dictionary) of all the numbers in the input list.

The keys of this map are the numbers from the list, and the values are their respective counts.

Finally, it uses a list comprehension to iterate through the frequency map and collect all numbers whose count is greater than 1.

____Complexity Analysis ___
Time Complexity: O(n)

Space Complexity: O(k)
Test cases
arr1: [1, 2, 3, 6, 3, 6, 1]
Expected: 1, 3, 6
arr2: [2, 1, 5, 4, 1, 3, 5]
Expected: 1, 5
arr3: [2, 3, 8, 3, 13]
Expected : 3

... is this what was expected to do???...
