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

Ex Input:
['e', 167, 4283, 'l', 247, 4197, 3397, 'Z', 'F', 2835, 4273, 'F', '4769', '6831', '5497', 'Z', 'g', 'Y', '2003', '2851', '9303', '6173', 'P', 'U', 'G', 'X', 7049, 'q'], ['z', 'p', 'L', 'A', 'o', 391, 'F', '4769', '6831', '5497', 'Z', 'g', 'Y', '2003', '2851', '9303', '6173', 'I', 8741, 3159, 't']

Ex Output:
F, 4769, 6831, 5497, Z, g, Y, 2003, 2851, 9303, 6173


Ex Input:
['y', 'b', 'A', 'K', 887, '9169', '1575', '5233', '1749', '5739', 'A', 'V', 8989], [3381, 5213, 9463, 8631, 2091, '9169', '1575', '5233', '1749', '5739', 'h', 1679, 8181]
