Solution: Maximum Number of Visible Points

Understand how to solve the maximum visible points problem by calculating angles between points and an observer. Learn to use sorting and the two pointers technique to find the largest subset of points visible within a given field of view, and handle edge cases like coincident points efficiently.

Statement

You are provided with an array, points, an integer angle, and your location, where points[i] = [x_i, y_i] and location = [pos_x, pos_y], both representing integer coordinatesInteger coordinates refer to points on a plane where x and y values are whole numbers. on the X-Y plane.

You initially face directly east from your fixed location and cannot move. In other words, pos_x and pos_y cannot be changed. However, you can rotate to adjust your viewing direction. Your field of view, measured in degrees, is specified by the angle, representing the width of visibility. If you rotate counterclockwise by an angle $d$ , your visible field spans the inclusive range of angles $[d-\frac{angle}{2}, d+\frac{angle}{2}]$ ...
