#include<bits/stdc++.h>
using namespace std;
int main(){
     long long a,b,c,d;
     cin>>a>>b>>c;
     d= (c-a-b);
      if( d>0&&d*d>4*a*b    ) cout<<"Yes";
      else cout<<"No";
    return 0;
}

### Prompt

Develop a solution in CPP to the problem described below:

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<bits/stdc++.h>
using namespace std;
int main(){
     long long a,b,c,d;
     cin>>a>>b>>c;
     d= (c-a-b);
      if( d>0&&d*d>4*a*b    ) cout<<"Yes";
      else cout<<"No";
    return 0;
}
