TASK DEFINITION: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
PROBLEM: ['d', 897, 't', 1807, 'k', 'P', '5013', '1811', '9411', 'U', 'z', '2793', '3221', '5643', 'j', '1793', '9507', 'J', '6147', 'i', '4383', '723', 'z', 'c'], [2741, 'D', 5443, 'Z', 'k', 129, 3339, 'k', 'T', 'P', '5013', '1811', '9411', 'U', 'z', '2793', '3221', '5643', 'j', '1793', '9507', 'J', '6147', 'i', '4383', '723', 'd', 4353]

SOLUTION: P, 5013, 1811, 9411, U, z, 2793, 3221, 5643, j, 1793, 9507, J, 6147, i, 4383, 723

PROBLEM: [621, 7677, 'b', '889', '6721', 'H', 'd', 'S'], [8151, 'F', 'b', '889', '6721', 'h', 4123]

SOLUTION: b, 889, 6721

PROBLEM: ['h', 'l', 8607, '5319', 'H', '6243', '2877', 'C', 'B', '8971', 'x', '4303', 'p', 'w', 9199], ['d', 'h', 'c', '5319', 'H', '6243', '2877', 'C', 'B', '8971', 'x', '4303', 'p', 'D', 2595, 'O', 6071, 1605, 'p', 6373]
