#include <iostream>
#include <stdio.h>
using namespace std;
int main(){
  long a,b,c;
  scanf("%ld %ld %ld",&a,&b,&c);
  long d=c-b-a;
  if(d>0&&4*a*b<d*d)printf("Yes");
  else printf("No");
}
### Prompt

Generate 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

Output

Yes

### Response

```cpp
#include <iostream>
#include <stdio.h>
using namespace std;
int main(){
  long a,b,c;
  scanf("%ld %ld %ld",&a,&b,&c);
  long d=c-b-a;
  if(d>0&&4*a*b<d*d)printf("Yes");
  else printf("No");
