        For i = 0:

            j = 1: 0 + 1 = 1 (odd) → do not append
            j = 2: 0 + 2 = 2 (even) → append 2
        For i = 1:
            j = 0: 1 + 0 = 1 (odd) → do not append
            j = 1: 1 + 1 = 2 (even) → append 2
            j = 2: 1 + 2 = 3 (odd) → do not append
        For i = 2:

            j = 1: 2 + 1 = 3 (odd) → do not append
            j = 2: 2 + 2 = 4 (even) → append 4
        For i = 3:
            j = 0: 3 + 0 = 3 (odd) → do not append
            j = 1: 3 + 1 = 4 (even) → append 4
            j = 2: 3 + 2 = 5 (odd) → do not append
        For i = 4:
            j = 0: 4 + 0 = 4 (even) → append 4
            j = 1: 4 + 1 = 5 (odd) → do not append
            j = 2: 4 + 2 = 6 (even) → append 6
            
Final Output:

After all iterations, the list l would contain the values [0, 2, 2, 2, 4, 4, 4, 6].
