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:
['g', 'o', 1257, 'c', 'g', '3073', '4251', '4165', 'l', '9111', '4827', '7337', '7183', 'p', 9513, 1059, 909], [447, 1419, 'R', 'k', 'p', 'g', '3073', '4251', '4165', 'l', '9111', '4827', '7337', '7183', 'c', 'Q', 2133, 't']
Answer:
g, 3073, 4251, 4165, l, 9111, 4827, 7337, 7183
