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: [8913, 1007, 'V', '7653', '3567', '475', '1845', '7613', '7485', 't', '9401', '8273', 'A', 'j', 'R', 'q', '10003', '2381', 'I', 'a', 'w', 'b', '7627', '1749', 'z', 'C', 3209, 'w', 'O', 1513, 4853, 'b', 6593], [3153, 1647, 7695, 'R', 2887, 'q', 'f', 't', 'W', 9037, 7251, 'Y', 'E', 2971, 'l', '7653', '3567', '475', '1845', '7613', '7485', 't', '9401', '8273', 'A', 'j', 'R', 'q', '10003', '2381', 'I', 'a', 'w', 'b', '7627', '1749', 'z', 't', 'V', 'j', 5575, 9139, 'k', 'l', 867, 7837, 9807, 'j', 5533, 'I', 8905, 'S', 'n', 'z']
Solution: 7653, 3567, 475, 1845, 7613, 7485, t, 9401, 8273, A, j, R, q, 10003, 2381, I, a, w, b, 7627, 1749, z
