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

Now, solve this: ['d', 8373, 5343, 'Z', 1391, 4633, 4233, 'U', 2511, 9081, 8211, 's', 'W', 2155, 7713, 'S', 5693, 'U', 'F', 2879, 't', 8159, 'Z', 'A', 'l', 'P', '5881', 'O', 'D', 'C', '6647', 'O', 'b', '7601', '611', '421', '6145', 'W', '3971', 's', 'u', '1899', 'X', '37', '8033', '1745', 'l', 'k', 'p', '263', '6015', '3551', 'n', 'h', 'Z', 'F', 'b', 2279, 'i', 15, 'a'], ['T', 4717, 'T', 'T', 'x', 9705, 7149, 's', 5603, 4719, 'U', 2475, 4191, 'R', 1631, 8125, 'G', 'e', 149, 8925, 'k', 8769, 8317, 8639, 5983, 'w', '5881', 'O', 'D', 'C', '6647', 'O', 'b', '7601', '611', '421', '6145', 'W', '3971', 's', 'u', '1899', 'X', '37', '8033', '1745', 'l', 'k', 'p', '263', '6015', '3551', 'n', 'h', 'o', 8579, 9183, 'N', 'd', 'I', 4403, 1187, 7857, 8165, 4237, 's']
Solution:
5881, O, D, C, 6647, O, b, 7601, 611, 421, 6145, W, 3971, s, u, 1899, X, 37, 8033, 1745, l, k, p, 263, 6015, 3551, n, h
