 }
### Prompt

Please formulate a Cpp solution to 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 <bits/stdc++.h>
using namespace std;
 int main() {
   int64_t a,b,c;
   cin>>a>>b>>c;
   if(c-a-b>0&&4LL*a*b<(c-a-b)*(c-a-b)){cout<<"Yes"<<endl;}
   else{cout<<"No"<<endl;}
              
 }
