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

['B', 'r', 5629, 4409, 7197, 'N', 'x', 'I', '6145', 'i', 'Q', '1033', '2945', 'K', '4931', 'y', 6505, 9149, 'E', 3067, 819], [2523, 'f', 2623, 'I', '6145', 'i', 'Q', '1033', '2945', 'K', '4931', 'a', 5449, 9193, 6325, 'i', 6901, 'E']
I, 6145, i, Q, 1033, 2945, K, 4931

[7675, 6429, 'Y', 'J', '6533', 'o', '47', '6333', 'W', 'J'], [6609, 2621, '6533', 'o', '47', '6333', 'm', 'k', 2605, 'd']
6533, o, 47, 6333

['B', 8357, '1209', '15', 'r', 'O', 'P', '4141', '6893', 'w', 'J', 'S', 'p'], [1971, 325, 1173, 4423, 6429, '1209', '15', 'r', 'O', 'P', '4141', '6893', 'o', 'R', 'G']
