1620. Coordinate With Maximum Network Quality

You are given an array of network towers towers, where towers[i] = [xi, yi, qi] denotes the ith network tower with location (xi, yi) and quality factor qi. All the coordinates are integral coordinates on the X-Y plane, and the distance between the two coordinates is the Euclidean distance. You are also given an integer radius where a tower is reachable if the distance is less than or equal to rad
