编写一个代码来找出可以绘制多少非重叠的斜率+1线。找出有多少组共线线段。 [英] write a code to find out how many non-overlapping line of slope +1 can be drawn. Find out how many sets of collinear line segments are present.

问题描述

有'n'个点 - （x1，y1），（x2，y2），（x3，y3），....，（xn，yn）。任意两个点（xi，yi）和（xj，yj）可以通过一条直线连接。

找出可以绘制多少非重叠的斜率+1线。找出存在多少组共线线段（当存在至少两个线段时称为一组）

There are 'n' points -(x1,y1),(x2,y2),(x3,y3),....,(xn,yn). Any two points(xi,yi) and (xj,yj) can be connected by a straigth line.
Find out how many non-overlapping lines of slope +1 can be drawn. Find out how many sets of collinear lines segments are present.(It is called a set, when at least two lines segments are present)

推荐答案

我们不做你的作业：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！



如果遇到具体问题，请询问相关问题，我们会尽力提供帮助。但我们不打算为你做这一切！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
