TASK DEFINITION: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
PROBLEM: ['U', 6489, 'o', 'e', 'Z', 'G', '8175', 'r', '1915', '8587', '8845', 'I', 'B', 'R', 'N', 9533, 'd'], ['U', 4287, 'f', 'R', 1407, 3893, 6739, 'o', 'e', 'Z', 'G', '8175', 'r', '1915', '8587', '8845', 'Z', 2981, 'i', 'a', 'k', 5909, 'S', 9997]

SOLUTION: o, e, Z, G, 8175, r, 1915, 8587, 8845

PROBLEM: ['L', 1653, 4833, 3597, 'B', 'A', 'g', '6735', '6737', '6929', '3051', 'v', '1223', '497', 'K', 4721, 'L', 'H', 'F', 'y', 2849], [9635, 3451, 'A', 'g', '6735', '6737', '6929', '3051', 'v', '1223', '497', 'd', 'f']

SOLUTION: A, g, 6735, 6737, 6929, 3051, v, 1223, 497

PROBLEM: [8229, 'E', 245, 211, 8887, 'C', '7255', '9619', '9117', 'W', '6399', '6507', 'v', '8015', 'u', 's', 'U'], ['P', 8203, 'B', 'x', 8811, 4655, 'R', 3497, 8111, '7255', '9619', '9117', 'W', '6399', '6507', 'v', '8015', 'u', 'h', 'M', 4861, 3913, 'r']
