Patrate vecine

Proposed by GabiOffline
(2 comments)5.336 times displayed

In fiecare patrat al unui tabel 10 pe 10 se scrie cate un numar intreg, astfel incat diferenta dintre oricare doua numere scrise in patrate vecine sa fie cel mult 5.

Demonstrati ca doua dintre numere trebuie sa fie egale.

Observatie: doua patrate sunt considerate vecine daca au o latura comuna.
