Problem Statement

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

Output

If Raccoon can win without using the same move twice or more, print Yes; otherwise, print No.

Sample Input 1

10 3
4 5 6

Sample Output 1

Yes

The monster's health will become 0 or below after, for example, using the second and third moves.

Sample Input 2

20 3
4 5 6

Sample Output 2

No

Sample Input 3

210 5
31 41 59 26 53

Sample Output 3

Yes

Sample Input 4

211 5
31 41 59 26 53

Sample Output 4

No

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io::stdin;

fn main() {
    let mut input1 = String::new();
    let mut input2 = String::new();

    stdin().read_line(&mut input1).unwrap();
    let first_input: Vec<&str> = input1.split_whitespace().collect();
    let hp: u32 = first_input[0].parse().unwrap();
    let skill_num: usize = first_input[1].parse().unwrap();

    stdin().read_line(&mut input2).unwrap();
    let splitted_nums: Vec<&str> = input2.split_whitespace().collect();
    let mut sum = 0;
    let mut i = 0;
    while i < skill_num {
        let tmp: u32 = splitted_nums[i].parse().unwrap();
        sum += tmp;
        i += 1;
    }
    if hp <= sum {
        println!("Yes");
    } else {
        println!("No");
    }
}
