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 Go (1.6) (judge verdict: Wrong Answer)

package main

import (
	"fmt"
	"math"
)

func solution(a, b, c int) string {
	if math.Sqrt(float64(a))+math.Sqrt(float64(b)) < math.Sqrt(float64(c)) {
		return "Yes"
	}
	return "No"
}

func main() {
	var a, b, c int
	fmt.Scan(&a, &b, &c)
	fmt.Println(solution(a, b, c))
}
