Detailed Instructions: In this task, you are given two lists A,B. Find the longest common subsequence in the lists A and B.
See one example below:
Problem: [5797, 8817, '8297', 'b', 'U', 'b'], [5843, 8809, '8297', 'b', 'W', 'C']
Solution: 8297, b
Explanation: 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'].

Problem: ['D', 'M', 3063, 4737, 7969, 'R', 'S', 8469, 'j', 5603, 4911, 6755, 'u', 843, 4481, 'T', 'U', 't', 'Z', 7501, 6415, 'C', 4833, 'y', 'v', '6803', '5773', '5045', '5881', '6685', '7575', 'F', '4161', '5823', 'k', '8579', '5823', 'R', 'z', '1857', 'w', '569', '4017', 'y', 'x', '6157', 'u', 'b', 'x', 'm', 'P', 'a', 'J', 5843, 't', 'F', 'w', 6935, 2759, 7235, 'f', 'r', 7841, 897, 9887, 6795, 6455], ['m', 2297, 'q', 1985, 8697, 'Q', 757, 7211, 491, 5041, 5047, 5891, 'y', 'v', '6803', '5773', '5045', '5881', '6685', '7575', 'F', '4161', '5823', 'k', '8579', '5823', 'R', 'z', '1857', 'w', '569', '4017', 'y', 'x', '6157', 'u', 'c', 6861, 'C', 6723, 'j', 'p', 'V']
Solution:
y, v, 6803, 5773, 5045, 5881, 6685, 7575, F, 4161, 5823, k, 8579, 5823, R, z, 1857, w, 569, 4017, y, x, 6157, u
