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: ['l', 'm', 2691, 'n', 3775, 1229, 'K', 7285, 'H', 'N', 2179, 'p', 'Q', 'n', 'r', 's', 'T', 'P', 'a', 'u', 'C', '2671', '2503', '8911', '6633', '8745', '2241', 'G', '5241', '2509', 'B', '4919', '9103', 'Z', 'R', 'M', 'x', 't', '1667', 'L', '8897', 'r', 6085, 7111, 'l', 'p', 1587, 'I', 'v', 'F', 9535, 4517, 1765, 'b', 5159, 1093], ['g', 'c', 4051, 6457, 'P', 'g', 3651, 's', 'z', 'C', '2671', '2503', '8911', '6633', '8745', '2241', 'G', '5241', '2509', 'B', '4919', '9103', 'Z', 'R', 'M', 'x', 't', '1667', 'L', '8897', 'N', 8175, 681, 'o', 'l', 3429, 'v', 'A', 1481, 8333, 9081, 'z', 'E']
Solution:
C, 2671, 2503, 8911, 6633, 8745, 2241, G, 5241, 2509, B, 4919, 9103, Z, R, M, x, t, 1667, L, 8897
