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 PHP (5.6.30) (judge verdict: Runtime Error)

<?php
# スペース区切りの整数の入力
fscanf(STDIN, "%d %d %d", $a, $b, $c);
if (bcsqrt(a, 100) + bcsqrt(b, 100) < bcsqrt(c, 100)) {
  echo "Yes\n";
} else {
  echo "No\n";
}
?>
