In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.

['H', 3635, 'N', 'c', '2297', 'U', 'W', 'j', '7741', 'u', '2283', 'B', 9737, 'n'], ['U', 2701, 'e', 'z', 'd', 3631, 'E', 'V', 'c', '2297', 'U', 'W', 'j', '7741', 'u', '2283', 'c', 'F', 'b']
c, 2297, U, W, j, 7741, u, 2283

[675, 'N', '7605', 'W', 'J', 'E', '2099', 'I', 'i'], ['T', 8995, 'E', 'U', '7605', 'W', 'J', 'E', '2099', 'R', 3629, 977]
7605, W, J, E, 2099

[4551, 'l', 'o', 'N', 's', 1389], ['u', 3233, 'o', 'N', 'G', 7431]

o, N
