Teacher: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
Reason: 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'].

Now, solve this instance: ['X', 'F', 'w', 8555, 1703, 'o', 7033, 'Q', 'A', 'C', '1293', '3769', 'J', '9397', '5647', 'B', '5983', 'k', '5809', 'f', 'j', 'f', 'T', '9757', 'm', 't', 'F', 'O', '139', 'N', 'I', 'e', '1875', 'i', 'h', '8475', 'B', 's', 'x', 'W', 'm', 6589, 4335, 711, 'H', 'f', 'j', 5469, 'l'], ['q', 'm', 8989, 8749, 'E', 5197, 9035, 6977, 'l', '1293', '3769', 'J', '9397', '5647', 'B', '5983', 'k', '5809', 'f', 'j', 'f', 'T', '9757', 'm', 't', 'F', 'O', '139', 'N', 'I', 'e', '1875', 'i', 'h', '8475', 'B', 's', 'x', 'W', 'N', 'N', 'B', 8885, 6737, 67, 7741, 'A', 'H', 2659, 'r', 'd', 'x', 9853, 'd', 671, 'C', 'S', 6867, 'R', 7985, 'i', 8385, 9135, 'B', 3157]
