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:
[1691, 9521, 'e', 9925, '153', '9657', 'F', '7671', 't', '4113', 'h', '1551', '4963', 'h', 'h', 'H', 2183, 1721, 'P', 1659, 9437, 6403, 2057], ['Y', 6145, '153', '9657', 'F', '7671', 't', '4113', 'h', '1551', '4963', 'h', 'P', 8925, 9233, 4019, 'E', 'm', 1063]
Answer:
153, 9657, F, 7671, t, 4113, h, 1551, 4963, h
