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:
['x', 7099, 9059, 865, 'S', 'l', 'V', 8579, 'r', 2823, '9603', 'c', '1545', '7041', 'g', 'd', '1281', '3849', 's', '3959', 'X', 'Q', 'V', 'C', 1583, 531, 'u'], ['T', 7357, 4783, 967, '9603', 'c', '1545', '7041', 'g', 'd', '1281', '3849', 's', '3959', 'U', 229, 'P', 'x', 'T', 681, 863]
Answer:
9603, c, 1545, 7041, g, d, 1281, 3849, s, 3959
