Encuentra si dos rectángulos se superponen

Dados dos rectángulos, encuentre si los dos rectángulos dados se superponen o no.
Tenga en cuenta que un rectángulo se puede representar mediante dos coordenadas, arriba a la izquierda y abajo a la derecha. Así que principalmente nos dan las siguientes cuatro coordenadas. 
l1 : Coordenada superior izquierda del primer rectángulo. 
r1 : Coordenada inferior derecha del primer rectángulo. 
l2 : Coordenada superior izquierda del segundo rectángulo. 
r2 : Coordenada inferior derecha del segundo rectángulo.
