Based on the provided positive and negative examples, it appears that
the function f returns a new list containing only the even numbers from
the input list, preserving their original order.

Positive examples:

    pos(f([1, 2, 3, 4], [2, 4])) - Even numbers: 2, 4
    pos(f([1, 1, 1], [])) - No even numbers
    pos(f([3, 2, 1], [2])) - Even number: 2
    pos(f([2], [2])) - Even number: 2
    pos(f([10, 1, 4], [10, 4])) - Even numbers: 10, 4

Negative examples:

    neg(f([1, 2, 3], [2, 3, 7])) - '3' and '7' are not even
    neg(f([1, 1, 1], [1, 1, 1])) - '1' is not even
    neg(f([4, 4], [4])) - Both '4's should be included
    neg(f([10], [])) - '10' is even and should be included
    neg(f([10, 1, 4], [9, 5])) - '9' and '5' are not even

In each positive example, the output list contains only the even numbers
from the input list, while in the negative examples, the output list
does not match this pattern.
