EscapeLight

#4806

Andrei se află într-un labirint format dintr-o matrice de camere, fiecare având unul dintre următoarele tipuri: 0: cameră cu bec stins, 1: cameră cu bec aprins, 2: cameră fără bec (inaccesibilă), 3: cameră cu întrerupător.

Camerele de tip 3 pot aprinde/stinge becurile altor camere. Andrei poate alege să apese sau nu întrerupătoarele întâlnite. El pornește dintr-o cameră dată și trebuie să ajungă într-o cameră destinație, deplasându-se doar prin camere aprinse.

Se cere determinarea distanței minime pentru a ajunge la destinație.
