A geometrical problem - Need help
By Rupai, 13 years ago, In English
My problem statement:

You are given N (N<=1000) points in X,Y co-ordinates. X and Y are both positive. Now, the problem is using maximum number of point you have to draw a straight line and also using maximum number of point you have to draw a 1/4 shape parabola. Actually, here you have to solve two problem at the same time. You can use any point to draw any one from those. You can use those point that are use to draw a straight line for 1/4 shape parabola.

Now all I need is your help to solve this problem. Please discuss your opinion.
