TASK DEFINITION: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
PROBLEM: ['b', 'Z', 'n', 'O', 'x', 'K', 'J', '5997', '8241', 'O', '9965', 'n', '6043', 'p', '8943', 'F', 'O', '2181', 'k', 833, 9001], [6221, 'H', 'w', 6543, 'o', 1523, 'W', 6091, 'T', 7021, 8161, 1111, 4653, 'x', 'K', 'J', '5997', '8241', 'O', '9965', 'n', '6043', 'p', '8943', 'F', 'O', '2181', 'j', 5791, 3573, 9639, 'a', 4089, 5045, 'e', 'i', 'S', 3157, 1767, 2199, 'P']

SOLUTION: x, K, J, 5997, 8241, O, 9965, n, 6043, p, 8943, F, O, 2181

PROBLEM: ['T', 'L', 9743, 2463, 945, 'n', 'z', '1331', '7235', '8333', 'a', '4137', 'b', '9779', 'Y', 4345, 3947], [9937, 7577, '1331', '7235', '8333', 'a', '4137', 'b', '9779', 'z', 6129, 1469, 3001]

SOLUTION: 1331, 7235, 8333, a, 4137, b, 9779

PROBLEM: ['P', 7189, 1215, 9107, 'i', 6803, '3991', '727', 'm', 'X', '3851', 'Y', 'i', 'x', '855', 'k', '9289', '287', 'w', 7913, 6453, 'G', 9253], [8413, 6687, 7307, 6521, 'h', 3663, 'c', 'x', 'F', 8979, 'b', 'h', '3991', '727', 'm', 'X', '3851', 'Y', 'i', 'x', '855', 'k', '9289', '287', 'u', 7615, 'b', 'o', 6297, 4031, 'k', 851, 'W', 4733, 4483, 'A']
