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:
[9011, 4503, 'H', 'C', 'B', 3531, 3689, 'R', 'u', 'k', 'p', 2205, 'u', 'O', 9371, 7117, 6009, 'u', 'r', 9463, 2653, '1577', '2363', '5053', 'D', 'X', 's', '5919', '899', 'R', 'K', '5085', '1897', 'z', '803', 'W', 'h', '141', '4119', '425', '151', '3965', 'f', 'h', '1507', 'p', 'y', '2401', 'j', 3453, 'R', 1009, 643, 7179, 'b', 359, 'r', 'f', 5267, 's'], ['j', 'X', 1635, 2003, 345, 'z', 'b', 'F', 8835, 'k', 6567, 8345, '1577', '2363', '5053', 'D', 'X', 's', '5919', '899', 'R', 'K', '5085', '1897', 'z', '803', 'W', 'h', '141', '4119', '425', '151', '3965', 'f', 'h', '1507', 'p', 'y', '2401', 'c', 7143, 4901, 8927, 507, 9755, 'c', 'U', 6107, 'T']
Answer:
1577, 2363, 5053, D, X, s, 5919, 899, R, K, 5085, 1897, z, 803, W, h, 141, 4119, 425, 151, 3965, f, h, 1507, p, y, 2401
