Random point in a circle

Print a point chosen uniformly at random inside the circle of radius $1$ centered at $(a,b)$.

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 $(a,b)$.
