This is Chuck, the triangular yellow bird in Angry Birds. Chuck is famously known for being able to break through multiple wooden obstacles. Chuck is shot off the slingshot with an initial speed of $v$. If Chuck hits a wooden obstacle with speed greater than or equal to $n$, it will break that obstacle, and its speed decreases by $n$. If Chuck hits a wooden obstacle with speed lower than $n$, it will stop immediately. Given integers $v$ and $n$, find how many wooden obstacles Chuck can breakthrough. You may assume that there are an infinite number of wooden obstacles available, so Chuck won’t run out of wooden obstacles to break.

You are given two integers $v$ and $n$ on the first and second lines respectively $(1 \le v, n \le 2 \cdot 10^8)$.

On the first line, output the answer described in the Problem Statement.
