#1536 Ecuatii

Să considerăm ecuaţii de gradul I, de forma: expresie_1=expresie_2. Expresiile specificate sunt constituite dintr-o succesiune de operanzi, între care există semnul + sau semnul - (cu semnificaţia binecunoscută de adunare, respectiv scădere). Fiecare operand este fie un număr natural, fie un număr natural urmat de litera x (litera x reprezentând necunoscuta), fie doar litera x (ceea ce este echivalent cu 1x).

De exemplu: 2x-5+10x+4=20-x. Observaţi că în ecuaţiile noastre nu apar paranteze şi necunoscuta este întotdeauna desemnată de litera mică x.

Scrieţi un program care să rezolve ecuaţii de gradul I, în formatul specificat în enunţul problemei.

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 Ecuatii 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.
