### 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
