New problem!
$\left [ 5 \right ]$Let $k,m,n$ be integers such that $1\le n\leq m-1\leq k$. Determine the maximum size of a subset $S$ of the set $\left \{ 1,2,3,...,k \right \}$ such that no $n$ distinct elements of $S$ add up to $m$.

P.S.:This is an ISL problem.

May be you're right.Look when the marathon started and how many problems it has.Now-a-days many persons are too busy to solve forum's problems.Even I don't have much time like today to type everything what I do all day long or look at forum's problems.
