Chouti was doing a competitive programming competition. However, after having all the problems accepted, he got bored and decided to invent some small games.

He came up with the following game. The player has a positive integer $n$. Initially the value of $n$ equals to $v$ and the player is able to do the following operation as many times as the player want (possibly zero): choose a positive integer $x$ that $x<n$ and $x$ is not a divisor of $n$, then subtract $x$ from $n$. The goal of the player is to minimize the value of $n$ in the end.

Soon, Chouti found the game trivial. Can you also beat the game?

The input contains only one integer in the first line: $v$ ($1 \le v \le 10^9$), the initial value of $n$.

Output a single integer, the minimum value of $n$ the player can get.
