1. Find coordinates of intersection A rectangle is called rectilinear if its edges are all parallel to coordinated axes. Such a rectangle can be described by specifying the coordinated of its lower-left and upper-right corners. Write a function: function solution($K,$L,$M,$N,$P,$Q,$R,$S); that given eight integers representing two rectilinear rectangles (one with lower-left corner (K,L) and upper right corner (M,N), and another with lower-left corner (P,Q) and upper-right corner (R,S)), returns the area of the sum of the rectangles. If the rectangles intersect the area of the intersection should be counted only once. The function should return -1 if the area of the sum exceeds 2,147,483,647. For example Given Integers: K= -4 L = 1 M = 2 N = 6 P = 0 Q = -1 R = 4 S = 3 **the function should return 42** * The area of the First rectangle is 30 and the area of the second rectangle is 16 and the area of their intersection is 4. Assume that * K,L,M,N,P,Q,R and S are integers within the range [-2147483648...2147483647]. * K<M * L<N * P<R * Q<S
