LeetCodeArrayHash TableMathGeometryEnumerationOpen on judge ↗

Given a 2D integer array circles where circles[i] = [xi, yi, ri] represents the center (xi, yi) and radius ri of the ith circle drawn on a grid, return the number of lattice points that are present inside at least one circle. Note: - A lattice point is a point with integer coordinates. - Points that lie on the circumference of a circle are also considered to be inside it. Example 1: Input:
