# Square Peg

You know the old saying: *You can’t fit a square peg in a
round hole*!

Well, obviously you can if the hole is big enough. I guess you can’t fit a square peg into a round hole that is sufficiently small.

Given the side length $L$ of a square peg and the radius $R$ of a circular hole, determine if a square with side length $L$ can be placed within a circle of radius $R$.

## Input

Input consists of two space-separated integers $L,R$ ($1 \leq L, R \leq 1\, 000$) on a single line.

## Output

If a square of side length $L$ can fit in a circle with radius
$R$, output a single line
with the phrase `fits`. Otherwise, the
square cannot fit within the circle then output a single line
with the phrase `nope`.
