In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
One example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution is here: 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'].

Now, solve this: ['d', 'e', 5219, 7181, 2111, 'd', 'x', 'b', 2953, 'v', 'Y', 'F', 't', 3071, 9685, 'r', 763, 'e', 'e', 7293, 'D', '3489', 'x', '5893', 'S', 'h', 'L', '8601', 'J', '5793', '9367', 'f', '2539', 'J', 'R', '4371', 'R', 'L', 'F', '3753', '9523', '9419', '5403', '2207', '2593', 'V', '4531', 'W', 'q', 2133, 'L', 8205, 17, 'T', 1501, 'P', 'Q', 5631, 6763, 'x', 'v', 7767, 'r', 'g', 'V'], [3321, 'l', 'n', 'D', 3305, 'i', 'b', 'P', 'k', 'v', 2049, 1453, 'O', 715, '3489', 'x', '5893', 'S', 'h', 'L', '8601', 'J', '5793', '9367', 'f', '2539', 'J', 'R', '4371', 'R', 'L', 'F', '3753', '9523', '9419', '5403', '2207', '2593', 'V', '4531', 'i', 1305, 'N', 'G', 5025]
Solution:
3489, x, 5893, S, h, L, 8601, J, 5793, 9367, f, 2539, J, R, 4371, R, L, F, 3753, 9523, 9419, 5403, 2207, 2593, V, 4531
