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:
['y', 3009, 4031, 'R', 'H', 45, 'q', 9437, 'J', 4905, 6279, 3933, 5489, '5805', '99', 'q', '909', '4093', 'O', 'q', '5711', 'E', 'z', 'M', 'p', '8727', 'q', 'X', 'c', 'D', 3675, 'I', 'f', 'a', 'H', 'k', 4989, 5245, 'V', 'O', 1659, 'l', 4433, 'F'], [8355, 'A', 'M', 941, 9397, 177, 'u', 5481, 163, 4907, 'q', '5805', '99', 'q', '909', '4093', 'O', 'q', '5711', 'E', 'z', 'M', 'p', '8727', 'q', 'X', 'c', 'X', 963, 9787, 3013, 743, 2193, 6399, 9301, 'F', 8587, 6545, 'p', 'u']
Answer:
5805, 99, q, 909, 4093, O, q, 5711, E, z, M, p, 8727, q, X, c
