#2353

Într-o pădure există plantați copaci pe N linii și M coloane. Copacii au diferite înălțimi. O zonă dreptunghiulară de copaci din cadrul pădurii trebuie tăiată. Pădurarul trebuie să aleagă dintre C zone, o zonă în care suma înălțimilor copacilor este maximă. Deoarece pădurarului îi plac numerele prime, el va alege o zonă în care suma înălțimilor copacilor este și un număr prim.
Determinați suma din enunț pentru zonele puse la dispoziție.
