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: [6423, 9981, 9625, 3859, 8917, 2505, 'N', 9057, 8367, 'J', 6887, 'b', 7915, 1899, 4559, 'd', '7449', '5903', 's', 'e', 'M', 'o', '9753', 'Y', 'W', '8209', '8563', '2721', '4183', 'G', '6575', 'F', '5019', 'y', 'r', 5731, 'g', 9705, 2421, 'X', 9483, 'Q', 't', 'w', 2633, 'b', 'j', 'y', 8845], ['d', 5593, 'p', 9823, 'z', 3339, 'T', 7741, 'P', 5001, 's', 3677, 'g', 7701, 'd', '7449', '5903', 's', 'e', 'M', 'o', '9753', 'Y', 'W', '8209', '8563', '2721', '4183', 'G', '6575', 'F', '5019', 'y', 'z', 'R', 'N', 'F', 7101, 'R', 7759, 7355, 'W', 't']
Solution: d, 7449, 5903, s, e, M, o, 9753, Y, W, 8209, 8563, 2721, 4183, G, 6575, F, 5019, y
