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 JavaScript (node.js v5.12) (judge verdict: Accepted)

process.stdin.resume();
process.stdin.setEncoding("utf8");
    var lines = [];
    var reader = require("readline").createInterface({
        input: process.stdin,
        output: process.stdout
    });
reader.on("line", (line) => {
    lines.push(line);
});

reader.on("close", () => {
    var e = lines[0].split(" "), h = Number(e[0]), a = Number(e[1]);
    var f = lines[1].split(" "), array = [];
    for(var i=0;i<a;i++){
        array.push(Number(f[i]));
    }
    var sum = array.reduce((x, y) => x + y);
    if(sum >= h){
        console.log("Yes");
    }else if (sum < h){
        console.log("No")
    }
    
});
