PROBLEM: [1201, 'x', 'Z', '1951', '6643', '4463', 'N', 'W', '4625', 'w', 'D', 3599, 'B', 2299], ['T', 'z', 'A', 'Z', '1951', '6643', '4463', 'N', 'W', '4625', 'w', 'T', 'M', 'M']

SOLUTION: Z, 1951, 6643, 4463, N, W, 4625, w

PROBLEM: ['w', 3897, 'U', 'a', '455', '6499', '8975', '9003', 'O', 'j', 'T', 'P', 'C', 'z', 5141, 1751, 6731, 'r'], ['B', 8071, 703, 'G', 885, 'Z', 2391, 1749, 4177, 'U', 'a', '455', '6499', '8975', '9003', 'O', 'j', 'T', 'D', 8751, 'y', 2941]

SOLUTION: U, a, 455, 6499, 8975, 9003, O, j, T

PROBLEM: ['h', 'h', 5397, 'j', 'U', 7947, 5299, 'M', '9421', 'm', '7245', 'Q', 'c', 'B', 'c', '9621', 'A', 'K'], ['q', 'n', 'o', 'X', 'i', 'D', 'j', 9065, 'M', '9421', 'm', '7245', 'Q', 'c', 'B', 'c', '9621', 'R', 'k', 8925, 'm', 9155, 'I', 2043]

SOLUTION:
M, 9421, m, 7245, Q, c, B, c, 9621
