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: [8155, 777, 4287, 1891, 'I', 's', 8233, 'c', 7639, 1735, 'R', 'e', 'D', 'N', 'e', 'e', 'K', '6783', '2737', 'd', '5885', '4405', '9891', '8067', '8869', 'b', 'P', '8423', '2807', '7749', 'L', 'q', '1381', 'u', '4383', '9703', 'L', '1057', 'f', '6895', 'N', 'E', 'Y', 'K', 2229, 4787, 'n', 105, 'O', 4089, 3273], [5255, 2207, 'G', 1187, 'E', 2095, 'g', 7901, 'k', 'z', 2721, 'E', 'Y', 'V', 'u', 7099, 6963, 'c', 1133, 't', 1649, 'l', 'f', 'D', 'N', 'e', 'e', 'K', '6783', '2737', 'd', '5885', '4405', '9891', '8067', '8869', 'b', 'P', '8423', '2807', '7749', 'L', 'q', '1381', 'u', '4383', '9703', 'L', '1057', 'f', '6895', 'N', 'C', 'v', 'w', 'H', 5887, 'r', 'p', 2869, 'o', 8425, 9345, 'V', 7107, 4319, 'M', 671]
Solution: D, N, e, e, K, 6783, 2737, d, 5885, 4405, 9891, 8067, 8869, b, P, 8423, 2807, 7749, L, q, 1381, u, 4383, 9703, L, 1057, f, 6895, N
