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

Let me give you an example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
The answer to this example can be: 8297, b
Here is why: 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'].

OK. solve this:
[6211, 'A', 'G', 4443, 4419, 'o', 51, '7437', '3219', 'o', 'I', 'N', 'n', 'b', 'm', '8691', 'd', 'm', 1283, 4827, 9727, 2419, 4179, 7475, 'c'], [6299, 3897, 'A', 909, 2343, 3419, 'S', '7437', '3219', 'o', 'I', 'N', 'n', 'b', 'm', '8691', 'o', 'Q', 6199, 'b', 'B', 7171, 1751, 'P']
Answer:
7437, 3219, o, I, N, n, b, m, 8691
