In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.

Ex Input:
[3539, 6661, 127, 883, 'j', 'i', 9169, 4635, '8533', 'w', 'B', 'x', '8345', '1367', '8023', '4489', '5083', 'A', '2295', '2737', 'Q', 'H', 'Q', 4829, 'h', 'e', 'L', 6905, 't'], [7275, 1425, 'r', 'G', 'c', 's', 'W', 'L', 'C', 'o', '8533', 'w', 'B', 'x', '8345', '1367', '8023', '4489', '5083', 'A', '2295', '2737', 'z', 'V', 4703, 'c']

Ex Output:
8533, w, B, x, 8345, 1367, 8023, 4489, 5083, A, 2295, 2737
