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:
[8729, 3555, 3681, 'k', 3469, 'B', 1521, 2041, 'M', 4351, 'X', 'V', '447', '8751', '2463', 'F', '4715', '7997', 'Q', 'K', 'w', 'l', '6297', '5199', '5403', 'c', 'v', 'h', '2219', '8645', 'h', '3653', 'o', '6773', 'u', 'B', 'b', 'p', 'w', 865, 9047, 9075], ['g', 8975, 'B', 'x', 6501, 'V', '447', '8751', '2463', 'F', '4715', '7997', 'Q', 'K', 'w', 'l', '6297', '5199', '5403', 'c', 'v', 'h', '2219', '8645', 'h', '3653', 'o', '6773', 'u', 'B', 'b', 'w', 'Q', 's', 'N', 'l', 'r', 4541, 8751, 3425, 9785, 'l', 9035, 3057, 7355, 2825, 'j', 'q', 487, 'Q', 'l', 'p', 's', 1237, 2589, 'h', 4879]
Answer:
V, 447, 8751, 2463, F, 4715, 7997, Q, K, w, l, 6297, 5199, 5403, c, v, h, 2219, 8645, h, 3653, o, 6773, u, B, b
