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.

#include <stdio.h>
int main(void){
  long int h,n,a[10000],sum=0;
  
  scanf("%ld%ld",&h,&n);
  for(int i=0;i<n;i++){
      scanf("%ld",&a[i]);
  }
  
  for(int i=0;i<n;i++){
      sum+=a[i];
      if(h<=sum){printf("Yes");return 0;}
  }
 printf("No");
  
  return 0;
