### B - Planet B

##### Languages: C, C++, Java, Python, ... (details)

In order to pass the entrance examination tomorrow, Fito has to study for $T$ more hours. Let's assume for a moment that he can travel to a Planet $B$ where time passes $X$ times faster as it does in our world (Planet $A$). That means, while ($X \times t$) hours pass in Planet $B$, $t$ hours pass in Planet $A$. How many hours will pass in Planet $A$ while Fito studies for $T$ hours in Planet $B$?

#### Input

The only line of input contains the two integers $T$ ($1 \leq T \leq 100$) and $X$ ($0 \leq X \leq 100$).

#### Output

Print one line with the number of hours that will pass in Planet $A$. The output will be considered correct if its absolute error is less than $10^{-3}$.  If there is no answer, print the string "There is no PLANet B".
