Detailed Instructions: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
See one example below:
Problem: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 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'].

Problem: ['q', 9869, 2113, 6537, 'b', 'f', 8313, 'L', 'L', 9591, '6865', '6559', 'K', 'o', '455', 'G', 'K', '9347', '2261', '5655', '8475', 'P', '8137', '4323', '9073', 'z', 'F', 'c', '937', '5841', '1231', '131', 'Z', 'u', 's', '4161', 'x', 'Q', 1621, 4771, 7041, 6591, 'v', 'C', 9105, 8749, 7117, 1863, 'V', 'w'], [647, 8557, 6811, 'D', 2157, 9451, 6771, 'd', 'L', 4627, 5233, '6865', '6559', 'K', 'o', '455', 'G', 'K', '9347', '2261', '5655', '8475', 'P', '8137', '4323', '9073', 'z', 'F', 'c', '937', '5841', '1231', '131', 'Z', 'u', 's', '4161', 'x', 'c', 'h', 'x', 'l', 'm', 'q', 'S', 8717, 7043, 'l', 'a']
Solution:
6865, 6559, K, o, 455, G, K, 9347, 2261, 5655, 8475, P, 8137, 4323, 9073, z, F, c, 937, 5841, 1231, 131, Z, u, s, 4161, x
