Teacher: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
Reason: Here, '8297, b' is the longest common subsequence in both the input lists [5797, 8817, '8297', 'b', 'U', 'b'] and [5843, 8809, '8297', 'b', 'W', 'C'].

Now, solve this instance: ['C', 'l', 7965, 'E', 9403, 8385, 2905, 'f', 9235, 'a', 'M', 'e', 'o', '7599', '631', 'X', '1093', '3229', '6731', '1295', 'W', '6515', 'G', '3063', '1023', 'o', 'm', '9855', '695', '8107', '6183', '2361', 'M', 'R', 'X', 7591, 'l', 'E', 4711, 'O', 'j', 761, 9157, 4407], ['r', 'J', 8989, 4791, 'P', 'b', 'K', 'j', 'a', 9633, 7431, 'e', 'o', '7599', '631', 'X', '1093', '3229', '6731', '1295', 'W', '6515', 'G', '3063', '1023', 'o', 'm', '9855', '695', '8107', '6183', '2361', 'M', 'R', 'G', 2383, 4343, 277, 'k', 8697, 'C', 2417, 2495, 2661, 9799, 5347, 387, 'Z', 'n', 's', 59, 6511, 4143]
Student:
e, o, 7599, 631, X, 1093, 3229, 6731, 1295, W, 6515, G, 3063, 1023, o, m, 9855, 695, 8107, 6183, 2361, M, R
