Skyline

#2728

Uitându-ne din New Jersey către New York, Manhattan, departe, în zare, se văd zgârie norii. De la distanță, nu distingem clădirile, ci numai o linie formată din segmente orizontale și verticale, așa numita skyline.

Determinați care este aria celui mai mare dreptunghi care se poate înscrie în skyline.
