Detailed Instructions: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
See one example below:
Problem: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 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'].

Problem: [8407, 'b', 'H', 'y', 'j', 563, '1229', '10005', 'S', 'n', '2521', '2723', '8183', 'l', '1277', '9727', 'i', 's', 8189, 'Y', 'T'], [2017, 'N', 523, 39, 'b', 'o', '1229', '10005', 'S', 'n', '2521', '2723', '8183', 'l', '1277', '9727', 'k', 'T', 'R', 8321, 3725]
Solution:
1229, 10005, S, n, 2521, 2723, 8183, l, 1277, 9727
