TASK DEFINITION: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
PROBLEM: ['r', 'g', '997', 'n', '631', '527', 'E', 'A', 'n', 'n', 'G', '1197', 'R', 'L', 'G', 'N', 2585], ['X', 5347, 'M', 'Z', 4615, '997', 'n', '631', '527', 'E', 'A', 'n', 'n', 'G', '1197', 'R', 'L', 'P', 'o']

SOLUTION: 997, n, 631, 527, E, A, n, n, G, 1197, R, L

PROBLEM: ['G', 9195, 'n', 'x', 'A', '3777', 'd', 'K', 'W', '1911', '93', '5157', 'j', 'd', 'L'], ['y', 'I', 8025, 5165, 4825, 'L', 'A', 10001, 'x', 'A', '3777', 'd', 'K', 'W', '1911', '93', '5157', 'E', 'b']

SOLUTION: x, A, 3777, d, K, W, 1911, 93, 5157

PROBLEM: ['a', 9255, 9403, 'X', '5185', '7073', 'C', '6365', '627', '6043', 't', 'm', '4273', 'f', 8149], ['m', 'U', 'Y', 3099, 'g', 2265, 'I', 'g', 'b', '5185', '7073', 'C', '6365', '627', '6043', 't', 'm', '4273', 'E', 905, 7047, 'c', 'd']

SOLUTION:
5185, 7073, C, 6365, 627, 6043, t, m, 4273
