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.

Solution in C (GCC 9.2.1) (judge verdict: Accepted)

    #include <stdio.h>
    #include <string.h>

    int main(void)
    {
        int n,h;
        scanf("%d %d",&h,&n);
        int a[n];
        for(int i=0;i<n;i++){
            scanf("%d",&a[i]);
            h=h-a[i];
            //printf("%d\n",h);
        }
        if(h <= 0){printf("Yes\n");}
        else{printf("No\n");}
        return 0;
    }
