Example Input: ['q', 6247, 7691, 'M', 'i', 3857, 'J', '249', 'j', '3315', 'Y', 'q', 'K', 'B', 'h', 'M', 'i', '3947', '8559', '1833', 'q', 'x', '1469', '7579', '421', 'F', 'y', 'c', '9043', 'r', 'N', 'O', 'N', 'Z', 'a', 8713, 'a', 2717, 'y', 'l', 't', 1815, 9507, 1713, 'N'], ['Z', 7463, 6215, 'r', 43, 'h', 3841, 9317, 'J', 'x', 6735, 'b', '249', 'j', '3315', 'Y', 'q', 'K', 'B', 'h', 'M', 'i', '3947', '8559', '1833', 'q', 'x', '1469', '7579', '421', 'F', 'y', 'c', '9043', 'r', 'N', 'O', 'N', 'Z', 'Q', 'c', 'B', 9989, 'd', 875, 1185, 7121, 5559, 'k', 2289]
Example Output: 249, j, 3315, Y, q, K, B, h, M, i, 3947, 8559, 1833, q, x, 1469, 7579, 421, F, y, c, 9043, r, N, O, N, Z

Example Input: [4839, 2307, '5609', 'V', 's', '7059', 'N', '3761', 'i', '161', '1987', 'N', 'J', 'h', 'k', 'P'], [2615, 't', 5171, 'V', 'q', '5609', 'V', 's', '7059', 'N', '3761', 'i', '161', '1987', 'N', 'p', 5261, 3251]
Example Output: 5609, V, s, 7059, N, 3761, i, 161, 1987, N

Example Input: ['A', 'u', 5665, '8617', '8033', '1739', '9837', 'f', 'D', '5639', 'l', 'k', 7931], [8847, 3509, 'a', 'X', 3031, '8617', '8033', '1739', '9837', 'f', 'D', '5639', 'l', 'n', 'z']
