Solution: Max Points on a Line

Explore how to calculate the maximum number of collinear points in a 2D plane by analyzing slopes between points. Understand slope calculation, slope grouping, and how to implement an efficient O(n^2) time complexity algorithm to solve this geometry problem.

We'll cover the following...

Statement

Given an integer array of points where points[i]=[xi,yi]\text{points}[i] = [x_i, y_i] represents a point on the X–Y plane, your task is to return the maximum number of points on the same straight line.

Constraints:

  • 1≤1 \leq points.length ≤300\leq 300 ...
