Teacher: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
Reason: 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 instance: [7627, 2525, '6217', 'g', 'j', '8203', 't', '2919', '7655', 's', '4769', 'n', 'b', 7779, 2405, 'e', 'y', 'S', 7205, 'E'], ['j', 'U', 'b', 2757, 'X', 5365, 'v', 'p', 307, '6217', 'g', 'j', '8203', 't', '2919', '7655', 's', '4769', 'n', 'L', 3979, 659, 6971, 5737, 1189, 5917, 'D', 'i', 'F']
Student:
6217, g, j, 8203, t, 2919, 7655, s, 4769, n
