Lee3

#4557

Se dă o matrice binara cu N linii și M coloane. Celulele cu numarul 0 sunt libere si se pot traversa. Celulele cu numarul 1 sunt ocupate si nu se pot traversa. Pentru K poziții date, se cere să se determine drumul de lungime minimă care pleacă de la poziția (i1, j1) și trece prin toate cele K poziții intermediare (nu contează în ce ordine), ajungând în final în poziția (i2, j2).
