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: ['N', 'h', 3867, 1243, 5661, 'Q', 8021, 'G', 'q', 'V', 'y', 'k', 'R', 5741, 4931, 'v', 4885, 1607, 'y', 'S', 'i', '8221', '2631', '5119', 'M', 'O', '1629', '4639', '2215', 'N', '1549', 'R', 'M', 'P', '5113', '5905', '4569', 'l', 'Q', 6869, 9553, 'N', 5433, 'm', 5971, 'V', 3993, 601, 'j', 'K', 1087, 1703], ['D', 'b', 'L', 'y', 527, 'j', 8203, 'e', 'i', 9161, 6507, 3271, 'M', 'y', 'S', 'i', '8221', '2631', '5119', 'M', 'O', '1629', '4639', '2215', 'N', '1549', 'R', 'M', 'P', '5113', '5905', '4569', 'l', 'P', 'e', 9951, 'e', 313, 'd', 'e', 'q', 7569, 1135]
Solution:
y, S, i, 8221, 2631, 5119, M, O, 1629, 4639, 2215, N, 1549, R, M, P, 5113, 5905, 4569, l
