Problem Statement

An elementary school student Takahashi has come to a variety store.

He has two coins, A-yen and B-yen coins (yen is the currency of Japan), and wants to buy a toy that costs C yen. Can he buy it?

Note that he lives in Takahashi Kingdom, and may have coins that do not exist in Japan.

Constraints

All input values are integers.

1 \leq A, B \leq 500

1 \leq C \leq 1000

Input

Input is given from Standard Input in the following format:

A B C

Output

If Takahashi can buy the toy, print Yes; if he cannot, print No.

Sample Input 1

50 100 120

Sample Output 1

Yes

He has 50 + 100 = 150 yen, so he can buy the 120-yen toy.

Sample Input 2

500 100 1000

Sample Output 2

No

He has 500 + 100 = 600 yen, but he cannot buy the 1000-yen toy.

Sample Input 3

19 123 143

Sample Output 3

No

There are 19-yen and 123-yen coins in Takahashi Kingdom, which are rather hard to use.

Sample Input 4

19 123 142

Sample Output 4

Yes

Solution in Rust (1.15.1) (judge verdict: Wrong Answer)

use std::io;


fn main() {

    let mut line = String::new();
    let _ = io::stdin().read_line(&mut line);
    let split: Vec<&str> = line.split_whitespace().collect();

    let a: i64 = split[0].parse().unwrap();
    let b: i64 = split[1].parse().unwrap();
    let c: i64 = split[2].parse().unwrap();
    let r = byomocha(a,b,c);
    println!("{}",r);

}

fn byomocha(a: i64 ,b: i64,c: i64) -> String {
    if c <= (a+b) {
        return "YES".to_string();
    } else {
        return "NO".to_string();
    }
}
