Solution: Max Points on a Line

Explore the method to find the maximum number of points aligned on the same straight line by calculating slopes between points. Learn how to use slope grouping and dictionary counting to identify collinear points efficiently. Understand the step-by-step algorithm with time and space complexity analysis to apply this pattern in coding interviews.

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:

  • 11 \leq points.length 300\leq 300 ...
