abq
Fie o matrice cu n
linii (numerotate de la 1
la n
) și m
coloane (numerotate de la 1
la m
) ce conține doar literele a
și b
. Se definește un drum de la o poziție (xs, ys)
la o alta (xf, yf)
ca fiind o succesiune de pași care pornește din coordonatele (xs, ys)
și ajunge în (xf, yf)
și care trece numai prin componente care memorează litera a
. La fiecare pas, de la o poziţie (i, j)
se poate trece într-una din poziţiile (i+1, j)
, (i-1, j)
, (i, j+1)
, (i, j-1)
. Lungimea drumului este dată de numărul de componente care compun drumul.
Având la dispoziție q
întrebări date sub forma a patru numere naturale xs ys xf yf
, trebuie să răspundeți pentru fiecare întrebare care este lungimea minimă a unui drum de la (xs, ys)
la (xf, yf)
care trece numai prin componente ce memorează litera a
. Dacă un astfel de drum nu există, veți afișa valoarea –1
.
