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:
[719, 'u', 733, 6671, 'C', 'A', 'p', 'p', 'C', 'h', 'B', 'd', 'S', '6339', '2013', '9527', '3259', 'd', '8465', '2871', 'Z', 'v', '4539', 'S', '7595', '113', 'y', 'o', 'z', 'y', '3131', '4515', '1047', '6377', 'E', 'u', 'q', '3181', '7171', 'K', 'F', 'i', 'X', 'K', 'w', 'Q', 4863], [425, 481, 4617, 1891, 'B', 'k', 'R', 'r', 'q', 'S', '6339', '2013', '9527', '3259', 'd', '8465', '2871', 'Z', 'v', '4539', 'S', '7595', '113', 'y', 'o', 'z', 'y', '3131', '4515', '1047', '6377', 'E', 'u', 'q', '3181', '7171', 'K', 'F', 'D', 'w', 6191, 831, 8895, 'k', 9699, 3193, 4725, 'q', 5971, 'x', 2577, 'K', 'P', 'e', 'w', 'e', 'U', 2925, 'O', 4595, 'Z', 'f', 3349, 'L', 'v']
Answer:
S, 6339, 2013, 9527, 3259, d, 8465, 2871, Z, v, 4539, S, 7595, 113, y, o, z, y, 3131, 4515, 1047, 6377, E, u, q, 3181, 7171, K, F
