Problem:
 Score : 100 points    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
