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: [233, 'A', 3231, 'J', 'E', 'D', 4999, 'l', '4039', '3911', 'l', '6825', '4531', 'Y', '3697', 'v', 'm', '5997', 'h', '2413', '8293', '3291', '3529', '4043', 'x', '7645', 'e', 3425, 'n', 'B', 'a', 'V', 9437, 1233, 'P', 'H', 5439], [1105, 'N', 1937, 'q', 6577, 7357, 155, 7973, '4039', '3911', 'l', '6825', '4531', 'Y', '3697', 'v', 'm', '5997', 'h', '2413', '8293', '3291', '3529', '4043', 'x', '7645', 'H', 'W', 4283, 'R', 1945]
Solution:
4039, 3911, l, 6825, 4531, Y, 3697, v, m, 5997, h, 2413, 8293, 3291, 3529, 4043, x, 7645
