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: [2167, 2159, 'Q', 'p', 's', 7677, 'E', 9329, 175, 'e', '8415', '7929', '663', '5629', '3063', 'X', 's', '8151', '6167', 'E', 'p', '3569', 'N', 'J', 'T', 'q', 'N', 'e', 'x', '6609', 'D', 'P', 'D', 7727, 7633, 'L', 8451], [3883, 5879, 'z', 'm', 3243, 9413, 3881, 'X', 7843, 5997, 'e', '8415', '7929', '663', '5629', '3063', 'X', 's', '8151', '6167', 'E', 'p', '3569', 'N', 'J', 'T', 'q', 'N', 'e', 'x', '6609', 'D', 'f', 'i', 1693]
Solution: e, 8415, 7929, 663, 5629, 3063, X, s, 8151, 6167, E, p, 3569, N, J, T, q, N, e, x, 6609, D
