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:
['P', 'p', 'r', 4083, 3365, 'O', 'c', 'I', 'Z', '9375', 'y', 'z', '1481', '225', '8929', 'n', 'I', 2077], ['Q', 8623, 8763, 'j', 2305, 'i', 'I', 'Z', '9375', 'y', 'z', '1481', '225', '8929', 'n', 'X', 'X', 's', 2333, 'I', 5549, 'j', 5453, 'I']
Answer:
I, Z, 9375, y, z, 1481, 225, 8929, n
