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<bits/stdc++.h>
using namespace std;

int main(){
    double a,b,c;
    cin >> a >> b>>c;

    double aa=sqrt(a);
    double bb=sqrt(b);
    double cc=sqrt(c);

    double sahen;
    double uhen;

    sahen = aa + bb - cc;
    uhen = 0;

    if(sahen < uhen){cout << "Yes" << endl; return 0;}
    cout << "No" << endl;
