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: [1401, 5467, 7309, 'l', 783, 'y', 'f', '4807', 'Q', '4241', '505', '655', '7623', '6053', '2327', 'n', 'Q', 'g', 'U', '3717', 'L', '8545', 'M', '3177', 's', '3469', '5575', '215', '6135', '5991', 'X', 'p', 'i', 2677, 'F', 'V', 1335, 6513, 1081], ['H', 'j', 6919, 9791, 8351, 7251, 'q', 8639, 8951, 'p', 537, 'J', 'H', 7021, 'l', 4599, 'r', 'X', 'V', 'y', 'f', '4807', 'Q', '4241', '505', '655', '7623', '6053', '2327', 'n', 'Q', 'g', 'U', '3717', 'L', '8545', 'M', '3177', 's', '3469', '5575', '215', '6135', '5991', 'c', 4041, 'f', 3337]
Solution:
y, f, 4807, Q, 4241, 505, 655, 7623, 6053, 2327, n, Q, g, U, 3717, L, 8545, M, 3177, s, 3469, 5575, 215, 6135, 5991
