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: ['Q', 'L', 3901, 3741, 'B', 8419, 2273, 'j', 'o', 'y', '4369', 'T', 'H', '8765', 'R', '9567', '6699', '1521', '7349', 'h', '1571', 'j', 'z', 6147, 'h'], [2115, 7503, 'y', '4369', 'T', 'H', '8765', 'R', '9567', '6699', '1521', '7349', 'h', '1571', 'j', 'j', 7717, 'F', 'v', 8675, 'k', 'R', 3975, 5579]
Solution:
y, 4369, T, H, 8765, R, 9567, 6699, 1521, 7349, h, 1571, j
