#1332

Se dă o tablă de șah formată din n linii și m coloane, definind n*m zone, unele dintre ele fiind libere, altele conținând obstacole. În zona de coordonate 1 1 se află un cal care se poate deplasa pe tablă în L, ca la șah, fără a părăsi tabla, fără a trece prin zone care conțin obstacole și fără a trece de două ori prin aceeași zonă.

Determinați o modalitate prin care calul poate ajunge în zona de coordonate n m – unde se află o căpiță de fân.
