Description

Traditionally after the Local Contest,judges and contestants go to their favourite restaurant, Alfredos PizzaRestaurant. 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 bigpizza for all instead of several small ones. They wonder whether it is possibleto put the big rectangular pizza on the surface of the round table such that itdoes not overhang the border of the table. Write a program that helps them!

Input

The input file contains several test cases.Each test case starts with an integer number r, the radius of the surface ofthe 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 widthand the length of the pizza, 1 ≤ w ≤ l ≤ 1000.

Output

Output for each test case whether theordered pizza will fit on the table or not. Adhere to the format shown in thesample output. A pizza which just touches the border of the table withoutintersecting it is considered fitting on the table, see example 3 forclarification.

Sample Input

38 40 60

35 20 70

50 60 80
