#include <stdio.h>
int main(){
  long long int a,b,c;
  scanf("%lld%lld%lld", &a, &b, &c);
  if(4*a*b < (c-a-b)*(c-a-b) && c-a-b > 0) {
    puts("Yes");

  }
}
### Prompt

Construct a Cpp code solution to the problem outlined:

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

### Response

```cpp
#include <stdio.h>
int main(){
  long long int a,b,c;
  scanf("%lld%lld%lld", &a, &b, &c);
  if(4*a*b < (c-a-b)*(c-a-b) && c-a-b > 0) {
    puts("Yes");
  }
  else {
    puts("No");
  }
