Solution: Max Points on a Line

Explore how to identify the maximum count of collinear points by calculating slopes between points on a 2D plane. Understand the role of slope calculation and dictionary counting to solve this geometry problem using nested loops. This lesson helps you implement an efficient O(n²) time complexity solution for line collinearity in coding interviews.

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 ...
