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

Example Input: ['e', 'W', 'x', 6581, 'y', 4191, 'u', 'B', '6197', '6435', '4975', '5435', 'r', '7329', '4033', 'k', 'j', '5373', '5673', 'd', 'V'], ['i', 'O', 'Z', 211, 1503, 'X', 4315, 'G', 'u', 'B', '6197', '6435', '4975', '5435', 'r', '7329', '4033', 'k', 'j', '5373', '5673', 't', 'C']
Example Output: u, B, 6197, 6435, 4975, 5435, r, 7329, 4033, k, j, 5373, 5673

Example Input: [7395, 6997, 'Z', 2015, 'v', '4045', 'F', 'O', 'N', 'k', '6013', 'C', 8179, 4675, 'x', 'k', 'V'], ['P', 'A', 'v', '4045', 'F', 'O', 'N', 'k', '6013', 'k', 7667, 3913, 5111, 1215, 'r', 'g']
Example Output: v, 4045, F, O, N, k, 6013

Example Input: ['L', 3871, '3809', '3127', '2479', '8183', 'D', '8263', 'U', 'i', 'p', 'n', 1901, 'O', 7669], ['h', 'U', '3809', '3127', '2479', '8183', 'D', '8263', 'U', 'V', 'x', 7305]
Example Output:
3809, 3127, 2479, 8183, D, 8263, U
