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

Example Input: [7319, 'V', 'f', 't', 'M', 'L'], [4655, 3353, 'f', 't', 'G', 1263]
Example Output: f, t

Example Input: [6453, 7881, 'D', 'X', '9799', 'Z', '1711', 'P', 'L', 'E', '5039', '1161', 'n', '6077', '685', 'F', 'C', 'Y', 2235, 823, 'q', 'S', 'R', 'K', 2809, 'o', 7605, 'L', 'V', 'D', 'R'], [1195, 'n', 5253, 7139, 4463, 10023, 'O', 'Y', 'X', '9799', 'Z', '1711', 'P', 'L', 'E', '5039', '1161', 'n', '6077', '685', 'F', 'C', 'L', 4321, 3545, 'G', 'G', 'h']
Example Output: X, 9799, Z, 1711, P, L, E, 5039, 1161, n, 6077, 685, F, C

Example Input: [5475, 'J', 'M', 'V', '7693', 'D', 'x', 'c', 2053, 7121, 'O'], [4761, 'u', 'V', '7693', 'D', 'x', 'k', 'r', 'I']
