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

['G', 9195, 'n', 'x', 'A', '3777', 'd', 'K', 'W', '1911', '93', '5157', 'j', 'd', 'L'], ['y', 'I', 8025, 5165, 4825, 'L', 'A', 10001, 'x', 'A', '3777', 'd', 'K', 'W', '1911', '93', '5157', 'E', 'b']
x, A, 3777, d, K, W, 1911, 93, 5157

['N', 7229, '4831', 'P', 'E', 7925], [3857, 'C', '4831', 'P', 'g', 'p']
4831, P
