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.

program example
	implicit none

	integer(8) a,b,c

	read(*,*) a,b,c
    
    if(dble(c)>dble(a)+dble(b)+2*sqrt(dble(a)*dble(b))) then
    	write(*,*) "Yes"
        goto 1
    else
    	write(*,*) "No"
        goto 1
        
    end if
