#3797 paths_sums

Se dau un arbore cu N noduri și rădăcina în nodul 1 al cărui muchii au lungimi exprimate prin numere naturale nenule și Q query-uri de forma u v. Pentru fiecare query să se afle suma lungimilor tuturor drumurilor distincte de la un nod aflat în subarborele cu rădăcina în nodul u la un nod aflat în subarborele cu rădăcina în nodul v modulo \( {10}^{9} + 7 \)(lungimea unui drum este egală cu suma lungimilor tuturor muchiilor ce îl alcătuiesc).

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

  • probleme la care rezolvarea presupune scrierea unui program complet
  • probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema paths_sums face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

  • Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
  • Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
