# Toast

*clink!*” sounds as the milk glasses touch. What is the radius of the table?

## Input

A single line containing three integers, $N$, $D$, and $T$.

We always have $2 \leq N \leq 10^4$, $100 \leq D \leq 10^9$ and $1 \leq T \leq 10^{8}$.

## Output

Output should contain two numbers $\ell $ and $h$, the lowest and highest possible radius of the table. Your answers may be off by at most $10^{-4}$. There will always be a possible radius for the table.
