[lang=hr] Prvi zadatak kojeg se Fran sjetio glasio je: Find the maximal cardinality $|S|$ of the subset $S \subset A=\{1, 2, 3, \dots, 9\}$ given that no two sums $a+b | a, b \in S, a \neq b$ are equal. I dok ga je u glavi riješio, već je prošao City Centar i krenuo prema Podsusedu. Budite marljivi kao i Fran i riješite ovaj zadatak. [/lang] [lang=en] The first problem Fran thought of was: Find the maximal cardinality $|S|$ of the subset $S \subset A = \{1, 2, 3, \dots, 9\}$ given that no two sums $a+b$ where $a, b \in S$ and $a \neq b$ are equal. While solving it in his head, Fran had already passed City Center and was heading toward Podsused. Be as diligent as Fran and solve this problem. [/lang]
