In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Example solution: 8297, b
Example 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: [7595, 'h', 7363, 'V', 5497, 4755, '4669', 'Q', '3479', '4453', 't', 'K', 'f', 's', 9785, 'v', 9859, 3775], ['V', 'K', '4669', 'Q', '3479', '4453', 't', 'K', 'h', 'Z', 'R', 1733, 9275]

Solution: 4669, Q, 3479, 4453, t, K
