The plane is divided into equal squares, which are filled with numbers from \textbf{0} to infinity in the form of a spiral in a clockwise direction: \includegraphics{https://static.e-olymp.com/content/9a/9a859b8a6b651bbd7d61d602ae443905249fec58.jpg} Given a positive integer \textbf{N}. Required to find two neighbors on the side or corner of the cell, the number of which sum to \textbf{N}. \InputFile The first line contains one integer \textbf{N} (\textbf{1} <= \textbf{N} <= \textbf{1000}). \OutputFile Bring two numbers through the gap is minimal neighbors in ascending order, and giving a total \textbf{N}.
