B"Ilya has recently taken up archaeology. He's recently found two numbers, written in the m-based notation. Each of the found numbers consisted of exactly n digits. Ilya immediately started looking for information about those numbers. He learned that the numbers are part of a cyphered code and the one who can decypher it can get the greatest treasure. After considerable research Ilya understood that to decypher the code, he should do the following: Help Ilya, find the key to the code. The first line contains two integers n, xe2 x80 x89m (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n, xe2 x80 x89m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89105, xe2 x80 x89m xe2 x80 x89> xe2 x80 x891). The second line contains the first found number, the third line contains the second found number. The numbers are recorded as a sequence of digits in the m-based notation. Each digit is an integer from 0 to m xe2 x80 x89- xe2 x80 x891. The digits in the line are written in the order from the most significant digits to the least significant ones. The given numbers can contain leading zeroes. Print n m-base digits. The resulting third number written in the m-based notation. Print the digits in the order from the most significant digits to the least significant ones."...
