Consider n chords on a circle, each defined by its endpoints. Describe an O(n lg n)- time algorithm to determine the number of pairs of chords that intersect inside the circle. (For example, if the n chords are all diameters that meet at the center, then the correct answer is (ⁿ₂).) Assume that no two chords share an endpoint.
