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: ['s', 'd', 'X', 4251, 'g', 'w', 7573, 6793, 5273, 7167, 'R', 'l', 'j', '4427', '463', '1991', '5707', '2981', '3903', '4623', '9111', '5893', '7329', '2701', '3863', '4133', 'e', '5251', '9473', 'J', 'A', 'I', 'i', 'e', '5975', '2567', '3139', 'a', '8691', 'F', 'W', 'U', 3967, 'K', 'y', 'W', 'h', 'B', 8969, 'q', 'A', 8971, 7163, 5787, 8393, 'M', 'i', 'V', 5563, 'U', 4241, 'M', 'Y', 6911], ['B', 1325, 'q', 'J', 'b', 4549, 'O', 1525, 7787, 'm', 4627, 7977, 3073, 7893, 1327, 3389, 'X', 'w', 'S', 'x', 7291, 1011, 6711, 'D', 'z', 6109, 7525, 117, 9209, 'R', 'l', 'j', '4427', '463', '1991', '5707', '2981', '3903', '4623', '9111', '5893', '7329', '2701', '3863', '4133', 'e', '5251', '9473', 'J', 'A', 'I', 'i', 'e', '5975', '2567', '3139', 'a', '8691', 'F', 'P', 'l', 'W', 6373, 's', 8231, 'N', 'R', 'H', 'E', 7771, 5087, 'Z', 'x', 'r', 9887, 'J', 'i', 1211, 2039, 'I', 3601]
Solution:
R, l, j, 4427, 463, 1991, 5707, 2981, 3903, 4623, 9111, 5893, 7329, 2701, 3863, 4133, e, 5251, 9473, J, A, I, i, e, 5975, 2567, 3139, a, 8691, F
