Random point in a circle

Input

One line contains three integers n~(0 < n \le 1000), $a$ and b~(-100 \le a, b \le 100).

Output

Print $n$ lines. Each line must contain two real numbers $x$ and $y$, where $(x,y)$ is a uniformly chosen point strictly inside the circle of radius $1$ centered at $(a,b)$.
