TASK DEFINITION: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
PROBLEM: [6971, 'd', 'J', 'p', 'F', 5463, 'F', 'P', 1897, 'J', 'O', 'j', 'H', 'y', '3659', '9455', 'P', '9829', 'm', 'Q', 7829, 'C', 5311], ['E', 'R', 'H', 217, 'J', 'O', 'j', 'H', 'y', '3659', '9455', 'P', '9829', 'm', 'T', 5849, 1449]

SOLUTION: J, O, j, H, y, 3659, 9455, P, 9829, m

PROBLEM: ['L', 5499, 'z', 'J', 'I', 't', 6291], [337, 5087, 'z', 'J', 'I', 'p', 'm']

SOLUTION: z, J, I

PROBLEM: ['P', 'p', 'r', 4083, 3365, 'O', 'c', 'I', 'Z', '9375', 'y', 'z', '1481', '225', '8929', 'n', 'I', 2077], ['Q', 8623, 8763, 'j', 2305, 'i', 'I', 'Z', '9375', 'y', 'z', '1481', '225', '8929', 'n', 'X', 'X', 's', 2333, 'I', 5549, 'j', 5453, 'I']

SOLUTION:
I, Z, 9375, y, z, 1481, 225, 8929, n
