In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
One example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution is here: 8297, b
Explanation: 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: [4589, 8561, 'w', 'I', 'M', 3469, '5359', '9641', 'e', 'R', '9513', 'I', '6097', '2611', 'm', '1197', 'C', 'E', 'O', 'o', 'T'], [2491, 'i', 'W', 'r', 4053, 'K', 'T', 939, 9293, 'p', 197, '5359', '9641', 'e', 'R', '9513', 'I', '6097', '2611', 'm', '1197', 'C', 'E', 'd', 2559, 'P', 9821, 9877, 2455, 's', 'o', 7045]
Solution:
5359, 9641, e, R, 9513, I, 6097, 2611, m, 1197, C, E
