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: ['y', 5087, 'y', 'Q', '8593', 'F', 'Q', 'U', 'U', 2579], [3899, 'Z', 'H', 2981, 2633, 'v', 'y', 'Q', '8593', 'F', 'Q', 'U', 'F', 'o', 8347]
Solution:
y, Q, 8593, F, Q, U
