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

Let me give you an example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
The answer to this example can be: 8297, b
Here is why: 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'].

OK. solve this:
[2087, 'V', 'e', 'q', 'Z', 'i', 7583, 's', 'l', 'I', 'd', 'r', '9409', '1035', '4757', 'G', '385', '3111', 'c', 'x', '4557', 'F', '1727', 'e', '9237', 'S', 'u', 'v', 'E', 4671, 'A', 'm', 't'], ['m', 'm', 's', 'l', 'I', 'd', 'r', '9409', '1035', '4757', 'G', '385', '3111', 'c', 'x', '4557', 'F', '1727', 'e', '9237', 'j', 'm', 'x', 'O', 'm', 9167, 4483, 1255, 7765, 'J', 'l', 'g', 'T', 'e', 'p', 'x', 'U']
Answer:
s, l, I, d, r, 9409, 1035, 4757, G, 385, 3111, c, x, 4557, F, 1727, e, 9237
