Difficulty—

Raccoon is fighting with a monster. The _health_ of the monster is $H$. Raccoon can use $N$ kinds of special moves. Using the $i$\-th move decreases the monster's health by $A_i$. There is no other way to decrease the monster's health. Raccoon wins when the monster's health becomes $0$ or below. If Raccoon can win without using the same move twice or more, print `Yes`; otherwise, print `No`. ## Constraints * $1 \leq H \leq 10^9$ * $1 \leq N \leq 10^5$ * $1 \leq A_i \leq 10^4$ * All values in input are integers. ## Input Input is given from Standard Input in the following format: $H$ $N$ $A_1$ $A_2$ $...$ $A_N$ [samples]
