We can do the following in 2-D plane where the pints are given in the form of (x.y).
For each selection of three points do the following: Find the area of the triangle of the three points. Let it be A. If A is zero then Print "Existence of Co-linear points" Break. This can be achieved in C(n,3) steps so the time complexity is n(n-1) (n-2)/6 = O(n^3). -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
