In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
One example: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution is here: 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'].

Now, solve this: [4821, 'U', 4243, 3043, 9027, 'j', 'Q', 9093, 5331, 2903, 3683, 'k', 'I', 3671, 4175, 2139, 'k', 339, '7779', '6757', '10017', 'E', 't', '4815', 'i', 'K', '9141', '6403', '761', '1295', '4617', 'o', 'C', '1509', '681', '5067', 'L', 'e', 'z', '7261', 'I', 'X', '5471', 'j', '3257', 't', 'c', 'Z', 'd', 'p', 't', 9041, 4211, 3791, 6797, 4993, 'v', 'Y', 'G', 8597, 6637, 'J', 's', 3669, 3391], [1737, 'y', 8281, 4095, 'I', 7939, 'G', 7517, 7387, 'G', 'l', 5865, 'F', 6055, 'C', 3293, 'M', 'Q', 'z', 2941, 'd', 6003, 'G', 'e', '7779', '6757', '10017', 'E', 't', '4815', 'i', 'K', '9141', '6403', '761', '1295', '4617', 'o', 'C', '1509', '681', '5067', 'L', 'e', 'z', '7261', 'I', 'X', '5471', 'j', '3257', 't', 'c', 'o', 'Y', 'M', 'I', 'b', 'j', 'G', 655, 4433, 'X', 'O', 'Z', 'm', 7143, 7167, 'q', 4259, 605, 7547, 'o', 'C', 8385, 7937, 4963, 'U', 3999, 7883, 'J', 'E']
Solution:
7779, 6757, 10017, E, t, 4815, i, K, 9141, 6403, 761, 1295, 4617, o, C, 1509, 681, 5067, L, e, z, 7261, I, X, 5471, j, 3257, t, c
