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']
Example solution: 8297, b
Example 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: [1243, 'u', 9459, 1823, 8453, 'X', 747, 1853, 'T', 'b', 3605, 'h', 3103, 'F', 'L', 8343, 's', '3213', 'h', '2905', 'Y', '9481', 'h', 'k', '8723', 'k', '9763', '313', '7061', '6677', '8523', '811', 'b', '4485', 'z', 'K', 'U', 'w', '5683', '4277', 'P', 'n', 'L', 'i', 1851, 'Q', 'd', 10005, 'p', 'v', 'D', 5627, 3209, 9393, 1371, 'o', 2275], [5773, 'I', 'd', 'S', 'I', 1657, 5669, 7849, 3849, 5499, 'f', 251, 's', '3213', 'h', '2905', 'Y', '9481', 'h', 'k', '8723', 'k', '9763', '313', '7061', '6677', '8523', '811', 'b', '4485', 'z', 'K', 'U', 'w', '5683', '4277', 'P', 'n', 'H', 2027, 'p', 'R', 2361, 'r', 'P', 'A', 427, 7933, 2705]
Solution: s, 3213, h, 2905, Y, 9481, h, k, 8723, k, 9763, 313, 7061, 6677, 8523, 811, b, 4485, z, K, U, w, 5683, 4277, P, n
