Grokking the Coding Interview Patterns in Python

Solution: Max Points on a Line

Explore how to determine the maximum number of collinear points in a 2D plane by using slope calculations between points. Understand the use of dictionaries to group points by slope and efficiently identify the largest set of points on the same line. This lesson helps you practice geometric problem-solving relevant to 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

  • points[i].length =2= 2

  • ...
