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: [201, 'O', 'd', 'w', 'P', 'c', 'D', 'd', 'f', 'N', 7515], ['f', 6135, 's', 'P', 'c', 'D', 'd', 'q', 7909, 9923, 4165]
Solution:
P, c, D, d
