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 LuaJIT (2.0.4) (judge verdict: Wrong Answer)

function split(text, delimiter)
  if text.find(text, delimiter) == nil then
    return { text }
  end 

  local splited_texts = {}
  local last_position

  for splited_text, position in text:gmatch("(.-)"..delimiter.."()") do
    table.insert(splited_texts, splited_text)
    last_position = position
  end 
  table.insert(splited_texts, string.sub(text, last_position))
  return splited_texts
end

local a = io.read()
local list = split(a, " ")
local have_money = tonumber(list[1]) + tonumber(list[2])
local price = tonumber(list[3])

if (have_money-price) > 0 then
    print("yes")
else
    print("no")
end
