abq

#3114

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.
