Alfredo’s Pizza Restaurant

題目來源：http://218.194.91.48/acmhome/problemdetail.do?&method=showdetail&id=1455

描述

    Traditionally after the Local Contest, judges and contestants
go to their favourite restaurant, Alfredos Pizza Restaurant. The contestants are really hungry after trying hard for five hours. To get their pizza as quickly as possible, they just decided to order one big pizza for all instead of several small ones. They
wonder whether it is possible to put the big rectangular pizza on the surface of the round table such that it does not overhang the border of the table. Write a program that helps them!

輸入

    The input file contains several test cases. Each test case starts
with an integer number r, the radius of the surface of the round table the contestants are sitting at.
Input is terminated by r=0. Otherwise, 1
≤ r ≤ 1000. Then follow 2 integer numbers w and l specifying
the width and the length of the pizza, 1 ≤ w ≤ l ≤ 1000.

輸出

    Output for each test case whether the ordered pizza will fit
on the table or not. Adhere to the format shown in the sample output. A pizza which just touches the border of the table without intersecting it is considered fitting on the table, see example 3 for clarification.
