Queries on Number of Points Inside a Circle

Understand how to determine the number of points within or on the edge of given circles based on their coordinates. This lesson helps you apply geometric concepts and coordinate analysis to solve queries effectively.

We'll cover the following...

Statement

Given an array of points, where each point is represented as points[i]=[xi,yi]\text = [x_i, y_i], which are the coordinates of the ithi^{th} point on an X-Y plane where some points may have identical coordinates. Additionally, given an array of queries, where each queries[j] =[xj,yj,rj]\text = [x_j, y_j, r_j] ...
