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:
[6759, 1053, 1155, 'O', '6949', 'v', 'D', '5869', 'h', 'Y', 'K', 'W', 'G', 6467, 'y', 'a', 9489, 5531, 'K'], ['o', 9631, '6949', 'v', 'D', '5869', 'h', 'Y', 'K', 'W', 'T', 'j', 9325, 3237]
Answer:
6949, v, D, 5869, h, Y, K, W
