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.

		Scanner scanner = new Scanner(System.in);
		int ytotal = scanner.nextInt();
		int xtotal = scanner.nextInt();
		int c = scanner.nextInt();
		
		if(Math.sqrt(xtotal) + Math.sqrt(ytotal) < Math.sqrt(c)) {
			System.out.println("Yes");
		}else {
			System.out.println("No");
