#3368

Bil Gheiț, patronul Companiei Macrosoft, vă pune la dispoziție o matrice cu n linii și n coloane care memorează numere naturale. Un drum în matrice care pornește de la poziția (1,1) și se termină la poziția (n,n) este constituit din componente adiacente două câte două pe linii și coloane. Costul drumului este egal cu suma costurilor componentelor prin care trece drumul. Determinați costul minim al unui drum care pornește de la poziția (1,1) și se termină la poziția (n,n) și domnul Bil Gheiț vă vă angaja imediat la compania sa pe post de fochist.
