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

Example Input: ['v', 4045, 'D', 'P', 181, 4575, 'E', 'X', 'f', 2495, 'b', 5507, 8921, 'H', 8327, '893', 'f', '4969', 'B', 'A', 'T', 'V', 's', 'W', 'p', '5059', '6969', '9305', '4813', 's', 'X', 'y', 487, 'o', 'j', 'H', 'M', 2043, 8101, 'r', 5675, 'H'], ['X', 2089, 517, '893', 'f', '4969', 'B', 'A', 'T', 'V', 's', 'W', 'p', '5059', '6969', '9305', '4813', 's', 'H', 'P', 'M', 'X', 'B', 'y', 183, 3033, 2469, 2793, 8975]
Example Output: 893, f, 4969, B, A, T, V, s, W, p, 5059, 6969, 9305, 4813, s

Example Input: [4817, 'A', '3155', 'W', 'm', 4061], [7701, 'P', '3155', 'W', 't', 'J']
Example Output: 3155, W

Example Input: [147, 2837, 'B', '1437', 'S', 'I'], [8597, 147, 'B', '1437', 'L', 8311]
Example Output:
B, 1437
