In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.

Let me give you an example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
The answer to this example can be: 8297, b
Here is why: Here, '8297, b' is the longest common subsequence in both the input lists [5797, 8817, '8297', 'b', 'U', 'b'] and [5843, 8809, '8297', 'b', 'W', 'C'].

OK. solve this:
['b', 8375, 'Q', 6199, 'Z', 9123, '3095', 'M', 'Q', '4449', 'y', 'W', 'w', 'd', 9821, 1147, 'b', 8947, 8651, 'x'], [9999, 7433, 7255, 'p', 'N', 613, 'J', '3095', 'M', 'Q', '4449', 'y', 'W', 'w', 'o', 'J', 8821, 'n', 8405, 7605]
Answer:
3095, M, Q, 4449, y, W, w
