Construct four points $$$a,b,c$$$ and $$$d$$$ on the two-dimensional plane that satisfy the following conditions:
- $$$x$$$ and $$$y$$$ coordinates of all points are integers, and their absolute values don't exceed $$$10^9$$$
- $$$a$$$ and $$$b$$$ are different, and $$$c$$$ and $$$d$$$ are different.
- Let $$$l$$$ be the line passing through $$$a$$$ and $$$b$$$, and let $$$m$$$ be the line passing through $$$c$$$ and $$$d$$$. Then,
- $$$l$$$ and $$$m$$$ are not parallel.
- the absolute values of $$$x$$$ and $$$y$$$ coordinates of the cross point of $$$l$$$ and $$$m$$$ are not less than $$$10^{27}$$$.
