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

Example Input: ['i', 'n', '7509', '7241', 'V', 'k', 205, 'H'], ['s', 4349, 7023, '7509', '7241', 'V', 'O', 't', 9237]
Example Output: 7509, 7241, V

Example Input: [8523, 2741, 'B', 2283, 2319, 5579, 4895, 1093, '6081', 'w', 'j', 'U', '8951', 'g', '3325', '6587', '4979', 'X', 'x', '8257', 'G', 2491], [17, 6185, '6081', 'w', 'j', 'U', '8951', 'g', '3325', '6587', '4979', 'X', 'x', '8257', 'n', 4549, 'g', 1859, 'f', 'B', 4639, 6413]
Example Output: 6081, w, j, U, 8951, g, 3325, 6587, 4979, X, x, 8257

Example Input: [8321, 8951, '7029', '1035', 'y', 'V', 1011], ['S', 6463, '7029', '1035', 'y', 'x', 'D', 7533]
