You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.

[5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
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'].

New input: ['t', 2989, 3157, 'b', 1557, 'K', '8567', '2441', '2323', '7003', '7789', '3921', '257', '27', '7923', '555', 'i', 'z', 'D', '4093', '3219', 'a', 'w', 'O', 'j', '2897', '4695', '4045', 'I', '191', '9325', '8039', 'w', 'o', 'T', '5599', 'i', 's', 8491, 8921, 'X', 'M', 'q', 'B', 'd', 9109, 9229, 6489, 1233, 'I', 1831, 1137, 2669, 'N', 'X', 'd', 1017, 'u', 6531, 9113, 'k', 'Z', 7353, 4519, 'Z', 4833], ['o', 8737, 7873, 'u', 4085, 'C', 1031, 9817, 1691, 'B', 6133, 'W', 6907, 2819, 2027, 'K', 'O', 4067, 5597, 'U', 'n', 1971, 'L', 'M', 785, 8831, 8047, 3615, 'C', '8567', '2441', '2323', '7003', '7789', '3921', '257', '27', '7923', '555', 'i', 'z', 'D', '4093', '3219', 'a', 'w', 'O', 'j', '2897', '4695', '4045', 'I', '191', '9325', '8039', 'w', 'o', 'T', '5599', 'b', 'z', 'Q', 7011, 'S', 'u', 'x', 'V', 7383, 'c', 'u', 2723, 'a', 2621, 'J', 7583, 3309, 'I', 4083, 5227, 'p', 'u', 'Z', 'd', 6529, 'C', 'D', 1155, 'p']
Solution:
8567, 2441, 2323, 7003, 7789, 3921, 257, 27, 7923, 555, i, z, D, 4093, 3219, a, w, O, j, 2897, 4695, 4045, I, 191, 9325, 8039, w, o, T, 5599
