Detailed Instructions: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
See one example below:
Problem: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 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'].

Problem: ['K', 4691, 'I', '2495', '1015', 'L', '581', 'b', 9477], ['k', 2419, 'd', 'I', '2495', '1015', 'L', '581', 'r', 's', 6673, 5755]
Solution:
I, 2495, 1015, L, 581
