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:
[5045, 1791, 6085, 7007, 9637, 'x', 3783, 5591, 'j', 4653, 'g', 6971, 2287, 'I', 4077, 'i', 'w', 8247, 6383, 1925, 9991, 4699, 1813, 'C', 8971, 'S', '4705', '9921', '2633', 'R', 'b', '5569', 'X', '5411', 'h', 'y', '8167', 'K', 'u', '4777', '1657', 'N', '9529', 'B', 'P', '4219', '8903', 'J', 'l', '6491', '103', '9033', 'N', '6607', 'u', 'd', 2971, 7159, 'Q', 'V', 'Q', 3939, 'G', 5987, 'B', 3511, 8965, 'z', 5001, 'P', 5643, 'N', 519, 'X', 'C', 4589, 8927, 4349, 'q'], ['o', 'I', 5109, 4587, 8433, 931, 6681, 6147, 4303, 'w', 8085, 'X', '4705', '9921', '2633', 'R', 'b', '5569', 'X', '5411', 'h', 'y', '8167', 'K', 'u', '4777', '1657', 'N', '9529', 'B', 'P', '4219', '8903', 'J', 'l', '6491', '103', '9033', 'N', '6607', 'd', 'r', 5927, 8409, 'y', 'x', 'n', 8721, 6237, 4879]
Answer:
4705, 9921, 2633, R, b, 5569, X, 5411, h, y, 8167, K, u, 4777, 1657, N, 9529, B, P, 4219, 8903, J, l, 6491, 103, 9033, N, 6607
