}
### Prompt

Create a solution in CPP for the following problem:

Does \sqrt{a} + \sqrt{b} < \sqrt{c} hold?

Constraints

* 1 \leq a, b, c \leq 10^9
* All values in input are integers.

Input

Input is given from Standard Input in the following format:


a \ b \ c


Output

If \sqrt{a} + \sqrt{b} < \sqrt{c}, print `Yes`; otherwise, print `No`.

Examples

Input

2 3 9


Output

No


Input

2 3 10


Output

Yes

### Response

```cpp
#include<iostream>

using namespace std; 

int main(void)
{
  long long a,b,c,d;
  cin>>a>>b>>c;
  d=c-a-b;
  
  if((d>0)&&(4*a*b)<(d*d)){
    puts("Yes");
  }else{
    puts("No");
  }
  
  return 0;
}
