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

Sample Input 4

211 5
31 41 59 26 53

Sample Output 4

No

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

firstinput = input("")
secondinput = input("")
firstinputsplit = firstinput.split(" ")
secondinputsplit = secondinput.split(" ")
H = int(firstinputsplit[0])
N = int(firstinputsplit[1])
firstcont = H <= 1000000000 and N <= 1000000
skill = 0
for i in secondinputsplit:
  skill = skill + int(i)
if firstcont == True and skill <= 10000:
  if H <= skill:
    print("Yes")
  else:
    print("No")
else:
  print("")
