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:
[8937, 'P', 'u', 'M', 821, 8083, 5417, 'd', 2331, 'l', 1809, 5073, 4425, 'n', 2639, 'j', 'F', 6487, '9003', '7483', '8263', '4817', '7495', 'C', '1567', 'M', 'H', '2595', 'F', '3133', 'f', 'g', '4431', '2647', '3193', 'Z', 'j', '5631', '3807', '1777', '9827', 'Q', '9819', '9489', 'q', 8657, 4997, 'g', 'N', 1031, 1625, 2849, 'N', 'J', 6237, 9483, 7391, 'X', 6065, 3061, 5873, 'F', 'z', 6297, 'j', 'K'], [9421, 'Q', 5529, 'g', 1155, 1539, 'd', 'S', 'K', 'S', 'u', 8613, 'U', 'j', 'F', 8405, 503, 361, 2453, '9003', '7483', '8263', '4817', '7495', 'C', '1567', 'M', 'H', '2595', 'F', '3133', 'f', 'g', '4431', '2647', '3193', 'Z', 'j', '5631', '3807', '1777', '9827', 'Q', '9819', '9489', 'Z', 'e', 'V', 'u', 'e', 4639, 913, 'N', 2005, 'L', 5865, 'T', 'C', 3931]
Answer:
9003, 7483, 8263, 4817, 7495, C, 1567, M, H, 2595, F, 3133, f, g, 4431, 2647, 3193, Z, j, 5631, 3807, 1777, 9827, Q, 9819, 9489
