It is known that \textbf{s} is the sum of \textbf{n} digits in the decimal system. Necessary to restore the original number \textbf{s} number \textbf{n}. But this task is very simple, so you need to choose a \textbf{n}, which is divided by \textbf{s}. \InputFile In a single line of input file contains the number \textbf{s} (\textbf{1} ≤ \textbf{s} ≤ \textbf{4000}). \OutputFile Necessary to bring the number \textbf{n}, which has the sum of digits is divisible by \textbf{s} and \textbf{s}. If some of these numbers, any output that contains a decimal less than \textbf{5·10^6} figures.
