#883
Traversare
Se consideră harta unei suprafețe deșertice, dată sub forma unei matrice cu n
linii și m
coloane, formată din n*m
zone. Fiecare zonă poate fi accesibilă sau inaccesibilă. Dintr-o zonă accesibilă se poate trece în altă zonă accesibilă învecinată cu prima pe linie sau pe coloană.
Un călător dorește să traverseze deșertul de la nord (prima linie) la sud(ultima linie). Pentru aceasta el poate sa aleagă oricare zonă accesibilă de pe prima line și dorește să ajungă pe ultima linie cu număr minim de pași.
