diff #

    # For each i from N-1 down to 0
    for i in range(n-1, -1, -1):

        first = 2 * i
        second = first + i + 1
        third = second + i + 1
        # Extend the sequence with the current i in the calculated positions
        # We need to ensure the sequence has exactly 3N elements

        # This part is complex and requires careful handling to avoid overlaps
