ISI CSB 2017 C6
Let P = {P1(x1, y1), P2(x2, y2), . . . , Pn(xn, yn)} be a set of n points located within a rectangle such that none of the points touches its boundary. The topleft corner of the rectangle is at the origin O(0, 0). A plane mirror is placed ... at angle θ2 (denoted by a dashed line), passes through only 2 points. You will get full credit only if your algorithm takes O(n log n) time.
