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: [767, 2129, 't', 8531, '5533', '8843', '5861', '33', '2291', 'n', 'd', '4883', 'p', '7139', 'Q', 'R', '9533', '8295', '707', '4137', 'z', 'c', 'A', '8557', '193', '559', 'U', 'G', 465, 9149, 'f', 7131, 'd', 2661, 'q', 1561, 659, 'x', 2787, 905, 701, 1487, 'a', 4411, 'G', 'j', 2093], [5807, 'R', 'G', 2219, 559, 'B', 103, 'w', 'Q', 'Q', 2381, 485, 'z', 3193, 'R', 1371, 'T', 't', 3765, 'w', 'G', '5533', '8843', '5861', '33', '2291', 'n', 'd', '4883', 'p', '7139', 'Q', 'R', '9533', '8295', '707', '4137', 'z', 'c', 'A', '8557', '193', '559', 'U', 'A', 'V', 'Y', 'u', 2657, 5505, 'a', 'L', 2931, 6681, 'I', 't', 'q', 'R', 'N', 2247]
Solution: 5533, 8843, 5861, 33, 2291, n, d, 4883, p, 7139, Q, R, 9533, 8295, 707, 4137, z, c, A, 8557, 193, 559, U
