#include<bits/stdc++.h>
using namespace std;

  long a,b,c;cin>>a>>b>>c;
  cout<<  ((4*a*b<(c-a-b)*(c-a-b) && c-a-b>0)?"Yes":"No");
}
### 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

Input

2 3 10


Output

Yes

### Response

```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
  long a,b,c;cin>>a>>b>>c;
  cout<<  ((4*a*b<(c-a-b)*(c-a-b) && c-a-b>0)?"Yes":"No");
}
