&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==Cerința==&lt;br /&gt;
Un filipinez cultivat are X cărți pe care dorește să le vândă. Pentru aceasta, el merge pe strada Plopilor fără soț unde se află n case. Acesta știe că în fiecare dintre cele n case se vor vinde un număr de cărți.&lt;br /&gt;
&lt;br /&gt;
Filipinezul cultivat începe să vândă de la o casă a și trece pe la toate casele succesive până când nu mai are cărți de vândut.&lt;br /&gt;
&lt;br /&gt;
Determinați intervalul minim lexicografic [a, b] între care filipinezul să-și vândă cărțile, astfel încât să vândă un număr maxim de carți, mai mic sau egal cu X&lt;br /&gt;
&lt;br /&gt;
==Date de intrare==&lt;br /&gt;
Fișierul de intrare carti2.in conține pe prima linie numerele n și X, iar pe a doua linie n numere naturale separate prin spații reprezntând numărul de cărți pe care le va vinde la fiecare casă.&lt;br /&gt;
&lt;br /&gt;
==Date de ieșire==&lt;br /&gt;
Fișierul de ieșire carti2.out va conține pe prima linie numerele a și b, reprezentând minim lexicografic al numerelor caselor pentru care numărul de cărți maxim este vândut.&lt;br /&gt;
&lt;br /&gt;
==Restricții și precizări==&lt;br /&gt;
* 1 ≤ n ≤ 100.000&lt;br /&gt;
* 1 ≤ X ≤ 1.000.000.000&lt;br /&gt;
* numerele de pe a doua linie a fișierului de intrare vor fi mai mici decât 1.000.000&lt;br /&gt;
==Exemplu==&lt;br /&gt;
carti2.in&lt;br /&gt;
&lt;br /&gt;
 5 9&lt;br /&gt;
 1 2 3 4 5&lt;br /&gt;
carti2.out&lt;br /&gt;
&lt;br /&gt;
2 4&lt;br /&gt;
==Explicație==&lt;br /&gt;
Intervalul [2, 4], deoarece 2 + 3 + 4 = 9&lt;br /&gt;

==Explicație cod==&lt;br /&gt;
Acesta este un program Python care primește date de intrare din fișierul &amp;quot;carti2.in&amp;quot; și scrie datele de ieșire în fișierul &amp;quot;carti2.out&amp;quot;. În esență, programul primește un număr n și un număr x, reprezentând numărul de cărți și suma de bani disponibile, respectiv, și o listă de prețuri pentru fiecare carte. Scopul programului este de a găsi o pereche de indici (st, dr) astfel încât suma prețurilor de cărți de la st la dr să fie maximă și mai mică sau egală cu x.&lt;br /&gt;
&lt;br /&gt;
Funcțiile definite în cod includ:&lt;br /&gt;
&lt;br /&gt;
validate_input: Această funcție verifică dacă valorile n și x sunt valide și, în caz contrar, aruncă o excepție.&lt;br /&gt;
read_input: Această funcție primește datele de intrare și le prelucrează pentru a crea o listă sp care reprezintă suma cumulată a prețurilor pentru fiecare carte, începând cu prima carte.&lt;br /&gt;
CautBin: Această funcție implementează o căutare binară pentru a găsi poziția la care suma prețurilor de la poz până la mijlocul intervalului este mai mare sau egală cu x. Această funcție este apelată în cadrul funcției find_books.&lt;br /&gt;
find_books: Această funcție parcurge lista sp și pentru fiecare index i găsește indexul j astfel încât suma prețurilor de cărți de la i la j este maximă și mai mică sau egală cu x.&lt;br /&gt;
Blocul principal al programului apelează funcțiile read_input și find_books, apoi afișează indicii st și dr găsiți prin intermediul funcției find_books. Dacă valorile pentru n sau x sunt nevalide, programul va afișa un mesaj de eroare.&lt;/div&gt;</summary>
