Gropi

#1486

Gigel a primit de la prietenul său Programatorul o hartă a grădinii acestuia. Grădina are forma dreptunghiulară şi harta pe care a primit-o Gigel conţine informaţii despre starea culturii de pomi fructiferi. Mai precis ea conţine înălţimile fiecărui copac şi zonele în care s-au săpat gropi dar încă nu au fost plantaţi copaci. Harta grădinii poate fi reprezentată sub forma unei table dreptunghiulare cu N linii, numerotate de la 1 la N de sus în jos, şi M coloane, numerotate de la 1 la M de la stânga la dreapta. În fiecare celulă se află un număr real corespunzător înălţimii copacului sau valoarea 0 corespunzătoare unei gropi.

Cunoscând coordonatele unui punct de pe hartă ajutaţi-l pe Gigel să determine pe care dintre cele 8 direcţii N, NE, E, SE, S, SV, V, NV corespunzătoare acestui punct se află cele mai multe gropi.
