Ranran has a set $s_v$ of $n$ vectors and an integer $d$. He is bored at Sunday so he decides to invent a new problem for you.
You need to give a set $s_p$ of points, size of which is $m$. You will pick up every point $(a_i, b_i)$ in $s_p$ and every vector $(x_j, y_j)$ in $s_v$. The pair $(a_i,b_i,x_j,y_j)$ is called good if and only if the line $(a_i + tx_j, b_i + ty_j), t\in \mathbb{R}$ visits exactly $d$ points in $s_p$. $s_p$ is good if and only if every pair satisfies the condition. You need to find out a good set of points.
Ranran thinks about it at a few sleepless nights thinking of Yangyang and solves it. Now he gives this problem to you. Can you solve it?
