# Math problems 6-8 grade

# Integer division by 5

There are $n$ stones on the table. For $1$ coin, you can do one of the following operations:
\begin{itemize}
\item
Pick up one stone from the table. \ textbf {You cannot perform this operation if there are no stones on the table}.
\item
Place another stone on the table.
\end{itemize}
What is the smallest number of coins you need to spend so that the number of stones on the table is divisible by $5$?
Please note that $0$ is divisible by any number, which means that if there are $0$ stones left on the table, then the condition of the problem is satified.
\InputFile
One integer $n$ ($0 \le n \le 10^9$) --- initial number of stones on the table.
\OutputFile
Print a single integer - the minimum number of coins that you need to spend so that the number of stones on the table is divisible by $5$.
\Note
In the first example, initially there are $0$ stones on the table. $0$ is divisible by $5$, so no coins need to be spent.
In the second example, you can pay one coin and take one stone from the table. Then there will be $0$ stones on the table, and $0$ is divided by $5$.
In the third example, you can pay one coin and put another stone on the table (thus, there will be $4$ stones on the table), and then pay another coin and put another stone on the table, thus getting $5$ stones, which is divided by $5$.
