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: ['a', 'j', 2259, 7115, 'U', 'R', 'b', 2563, 7369, 'n', 'C', '4963', '5983', '147', 'm', '4597', '63', '1717', 'k', '4853', '8219', 'y', '3241', '6661', '1913', '5301', 'e', '3067', 'h', 5795, 'b', 415, 4311, 3175, 'C', 9257, 'q'], ['X', 3785, 8497, 'g', 3823, 's', 6019, 'C', '4963', '5983', '147', 'm', '4597', '63', '1717', 'k', '4853', '8219', 'y', '3241', '6661', '1913', '5301', 'e', '3067', 's', 'F', 6161, 'f', 2543, 'V', 6733, 9613, 7983, 'i', 'J', 7361, 8365, 'A', 979, 1153]
Solution: C, 4963, 5983, 147, m, 4597, 63, 1717, k, 4853, 8219, y, 3241, 6661, 1913, 5301, e, 3067
