#include<bits/stdc++.h>

using namespace std;

typedef long long ll;

ll a,b,c;

int main() {
	cin>>a>>b>>c;
	puts(4*a*b<(c-a-b)*(c-a-b) && c>a+b? "Yes":"No");
	return 0;
} 
### Prompt

Please create a solution in cpp 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

### Response

```cpp
#include<bits/stdc++.h>

using namespace std;

typedef long long ll;

ll a,b,c;

int main() {
	cin>>a>>b>>c;
	puts(4*a*b<(c-a-b)*(c-a-b) && c>a+b? "Yes":"No");
	return 0;
