( 1986 ) B Three matrices PROGRAMMING

B"Chubby Yang is studying linear equations right now. He came up with a nice problem. In the problem you are given an n xe2 x80 x89 xc3 x97 xe2 x80 x89n matrix W, consisting of integers, and you should find two n xe2 x80 x89 xc3 x97 xe2 x80 x89n matrices A and B, all the following conditions must hold: Can you solve the problem? The first line contains an integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89170). Each of the following n lines contains n integers. The j-th integer in the i-th line is Wij (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89|Wij| xe2 x80 x89< xe2 x80 x891717). The first n lines must contain matrix A. The next n lines must contain matrix B. Print the matrices in the format equal to format of matrix W in input. It is guaranteed that the answer exists. If there are multiple answers, you are allowed to print any of them. The answer will be considered correct if the absolute or relative error doesn't exceed 10 xe2 x80 x89- xe2 x80 x894."...
