Given the task definition, example input & output, solve the new input case.
In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Output: 8297, b
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'].

New input case for you: [3077, 3479, 3379, 'D', 'i', 7403, 6449, 'n', 3311, 8523, 2007, 9041, '9979', '8433', 'h', '7755', 'W', '7535', 'K', '5085', 'l', 'p', 'u', '8259', '8973', '4387', '1031', 'I', 'V', '9833', 'P', 9541, 'X', 'q', 'e', 8843, 'k', 'U', 1453, 4579], [3897, 'o', 3035, 'f', 'X', 1053, 'i', 571, 4895, 1547, 'V', 'k', 9547, '9979', '8433', 'h', '7755', 'W', '7535', 'K', '5085', 'l', 'p', 'u', '8259', '8973', '4387', '1031', 'I', 'V', '9833', 'd', 'i', 833, 1633, 'L', 2351, 'P', 'b', 'R', 'v', 7271, 'z', 2735, 2549]
Output:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
