Problem Statement

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

Constraints

  • 1a,b,c1091 \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 ca \ b \ c

Output

If a+b<c\sqrt{a} + \sqrt{b} < \sqrt{c}, print Yes; otherwise, print No.

2 3 9
No

2+3<9\sqrt{2} + \sqrt{3} < \sqrt{9} does not hold.

2 3 10
Yes

2+3<10\sqrt{2} + \sqrt{3} < \sqrt{10} holds.
