La concursul “Miss & Mister Boboc” participă n perechi de elevi, despre fiecare elev cunoscându-se înălțimea. Numim grad de disproporționalitate al unei perechi este diferența în valoare absolută dintre înălțimile elevilor care formează perechea.

Să se determine perechea cu grad de disproporționalitate maxim.
