Detailed Instructions: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
See one example below:
Problem: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
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: ['W', 9995, 'v', 5035, 'a', 5219, 'E', 7715, 'X', 'b', 'p', 'c', 'e', 9023, 'G', 'T', 'T', '8503', '1323', 'l', '631', 't', '9405', '8061', 'y', 'k', '5121', '1641', 'f', '6115', '6083', '5281', 'w', 'U', '6085', '941', '7877', '5003', '4119', 'O', '8481', 'E', 'w', 'u', 'g', 'C', 'd', 'r', 4969, 'o', 7279, 'X', 6411, 'j', 'h', 'h', 8653, 1827, 'i', 2085, 'b', 'F', 'p', 2407, 'x', 8489, 'a', 'Y', 4003, 'C', 'I', 'I', 'b', 5747, 'q', 'D', 475], [2865, 'W', 'U', 3791, 'd', 5227, 'f', 7307, 581, 'o', 'C', '8503', '1323', 'l', '631', 't', '9405', '8061', 'y', 'k', '5121', '1641', 'f', '6115', '6083', '5281', 'w', 'U', '6085', '941', '7877', '5003', '4119', 'O', '8481', 'E', 'w', 'u', 'g', 'C', 'd', 'l', 2203]
Solution:
8503, 1323, l, 631, t, 9405, 8061, y, k, 5121, 1641, f, 6115, 6083, 5281, w, U, 6085, 941, 7877, 5003, 4119, O, 8481, E, w, u, g, C, d
