Problem Statement

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.

Sample Input 1

2 3 9

Sample Output 1

No

\sqrt{2} + \sqrt{3} < \sqrt{9} does not hold.

Sample Input 2

2 3 10

Sample Output 2

Yes

\sqrt{2} + \sqrt{3} < \sqrt{10} holds.

Solution in C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<iostream>
#include<math.h>

using namespace std;
int main ()
{
    long long a,b,c;
    double p,q,r,s=0;
    cin>>a>>b>>c;

        p=sqrt(a);
        q=sqrt(b);
        r=sqrt(c);
        s=p+q;
   if(s<=r)
        cout<<"Yes"<<endl;
    else
        cout<<"No"<<endl;
