Problem Statement

Does $\sqrt{a} + \sqrt{b} < \sqrt{c}$ hold?

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.

Constraints

• $1 \leq a, b, c \leq 10^9$
• All values in input are integers.

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.
