In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.

Example Input: ['F', 175, 'f', 8443, 3869, 'X', 8987, 's', 'x', 'r', '6805', '843', 't', 'g', 'T', '8865', 'K', '9607', 'G', '4521', 'z', 'E', 'T', 9337, 'B', 3133, 10013], [2067, 3211, 'U', 'S', 8949, 'N', 'r', '6805', '843', 't', 'g', 'T', '8865', 'K', '9607', 'G', '4521', 'z', 'Q', 1511, 'X', 1105, 3303, 'u', 8705, 'j']
Example Output: r, 6805, 843, t, g, T, 8865, K, 9607, G, 4521, z

Example Input: ['o', 'k', '8037', '2095', 'E', 'l'], [4673, 'J', '8037', '2095', 't', 'F']
Example Output: 8037, 2095

Example Input: [9195, 'C', 'Q', 4439, 'i', 'f', 'V', 'C', 777, 3431, 'd', 4175, 'i', 3031, 391, 4069, 'B', 9121, 709, 2225, 4501, '979', '579', '4923', 'Y', '7451', 'X', 'z', '3459', 'W', 'G', '3447', '2157', 'b', '5267', 'p', 'A', 'K', 's', '10021', '9341', '3113', '5243', '665', '1289', 'P', 'e', 2345, 9445, 'q', 'B', 'V', 2033, 2971, 4305, 'O', 'e', 'N', 'z', 9843, 5651, 2105, 'G', 'g', 'F', 6009, 's', 'T', 'm', 4129], ['R', 2527, 9713, 'n', 'P', '979', '579', '4923', 'Y', '7451', 'X', 'z', '3459', 'W', 'G', '3447', '2157', 'b', '5267', 'p', 'A', 'K', 's', '10021', '9341', '3113', '5243', '665', '1289', 'P', 'j', 'B', 'f', 'J', 677, 'l', 'r', 8249, 'X', 'U', 7323, 9177, 'Y']
Example Output:
979, 579, 4923, Y, 7451, X, z, 3459, W, G, 3447, 2157, b, 5267, p, A, K, s, 10021, 9341, 3113, 5243, 665, 1289, P
