In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Example solution: 8297, b
Example explanation: 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'].

Problem: [8669, 'v', 't', 9125, 'c', 961, 's', 1359, 'S', 3761, 3007, 2369, 5857, 4625, '2805', 'F', 'd', 'q', '1107', 'O', '4445', '873', 'Z', 'e', '7607', '5613', '3463', '9183', '1285', '4115', '3469', '8073', 'i', 'f', 7345, 145, 1319, 3851, 2825, 8837, 6077, 'x', 4647, 2355, 'w', 'q', 'F', 991, 409, 'M', 811, 7209], ['l', 'O', 3909, 'b', 'q', 'E', 'k', 7501, 'X', 'p', 'T', 153, 'g', 295, '2805', 'F', 'd', 'q', '1107', 'O', '4445', '873', 'Z', 'e', '7607', '5613', '3463', '9183', '1285', '4115', '3469', '8073', 'i', 'E', 'z', 5801, 'Q', 3515, 5075, 5465, 'N', 2225, 8347, 8855, 'E', 'L']
Solution: 2805, F, d, q, 1107, O, 4445, 873, Z, e, 7607, 5613, 3463, 9183, 1285, 4115, 3469, 8073, i
