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
