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:
['e', 'K', 8151, 'V', 'z', '8267', '8309', 'f', '4051', '4913', 'i', 'T', 'O', 'g', 'J', 'z', 'x', 551, 'h'], [209, 8121, 'F', 'e', 'a', 2857, 945, 7719, 'z', '8267', '8309', 'f', '4051', '4913', 'i', 'T', 'O', 'o', 6389, 'f', 8425, 4535, 'A', 5495]
Answer:
z, 8267, 8309, f, 4051, 4913, i, T, O
