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: [8813, 3541, '6067', '9613', 'c', 'I', '7385', 'N', '6677', '9411', '2147', '9177', 'G', 'R', 'H', 'B', 'K', 'j', 'y', 7173, 4831, 8997, 'd', 4869, 'y', 5879, 'Q', 9407, 'P', 'n', 'E'], ['T', 'H', 'W', 'c', 5913, 7797, 8727, 'i', 6001, 'I', 'T', '6067', '9613', 'c', 'I', '7385', 'N', '6677', '9411', '2147', '9177', 'G', 'R', 'H', 'B', 'K', 'j', 'q', 6093, 2317, 1465, 'B', 'W', 'f', 'i', 'k', 465, 445]
Solution: 6067, 9613, c, I, 7385, N, 6677, 9411, 2147, 9177, G, R, H, B, K, j
