#964 cod

Pentru codificarea textului unui mesaj s-a folosit codificarea ASCII, asociindu-se literelor mari ale alfabetului englez numerele distincte de la 65 la 90, literelor mici ale alfabetului englez numerele distincte de la 97 la 122, spaţiului numărul 32, iar punctului (.) numărul 46.

Fiecare linie a mesajului ce urmează a fi codificat, are cel mult 80 de caractere, textul lui fiind format din cuvinte separate printr-un singur spaţiu sau printr-un singur punct, iar cuvintele sunt formate numai din litere ale alfabetului

Codificarea textului mesajului este realizată astfel: fiecare cuvânt din text se scrie în ordine inversă, înlocuindu-se fiecare caracter cu şirul rezultat prin scrierea în ordine inversă a codului asociat acestuia. De exemplu codificarea caracterului z este şirul 221. Aceeaşi regulă de codificare se aplică atât spaţiului cât şi punctului.

Textul rezultat în urma codificării va conţine doar cifre, fără spaţii şi fără simboluri de punctuaţie.

să se scrie un program care să citească codificarea textului unui mesaj, să decodifice textul şi să afișeze

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 cod 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.
