In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
One example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution is here: 8297, b
Explanation: Here, '8297, b' is the longest common subsequence in both the input lists [5797, 8817, '8297', 'b', 'U', 'b'] and [5843, 8809, '8297', 'b', 'W', 'C'].

Now, solve this: ['M', 'j', 1171, 'm', 'b', 1747, 3763, 2865, 1319, 3185, 'o', 2607, 4849, 815, 6637, 'v', 'Q', 'V', '1795', 'k', '7003', 'Y', 'h', 'a', '2511', '1721', '5065', '2983', '9869', 'o', '4583', 'E', '4715', '8953', '7413', '3285', 't', 'G', 3947, 6941, 'Z', 'U', 'x', 5723, 9783, 'y'], ['i', 'R', 'G', 'c', 9109, 'Y', 'C', 8281, 'V', '1795', 'k', '7003', 'Y', 'h', 'a', '2511', '1721', '5065', '2983', '9869', 'o', '4583', 'E', '4715', '8953', '7413', '3285', 't', 'a', 3467, 'H', 695, 'I', 9585, 8649, 5367]
Solution:
V, 1795, k, 7003, Y, h, a, 2511, 1721, 5065, 2983, 9869, o, 4583, E, 4715, 8953, 7413, 3285, t
