Problem Statement

There are $N$ children, numbered $1, 2, ..., N$.

Snuke has decided to distribute $x$ sweets among them. He needs to give out all the $x$ sweets, but some of the children may get zero sweets.

For each $i$ ($1 \leq i \leq N$), Child $i$ will be happy if he/she gets exactly $a_i$ sweets. Snuke is trying to maximize the number of happy children by optimally distributing the sweets. Find the maximum possible number of happy children.
