Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
You have r red and b blue beans. You'd like to distribute them among several (maybe, one) packets in such a way that each packet:
* has at least one red bean (or the number of red beans r_i ≥ 1);
* has at least one blue bean (or the number of blue beans b_i ≥ 1);
* the number of red and blue beans should differ in no more than d (or |r_i - b_i| ≤ d)
Can you distribute all beans?
Input
The first line contains the single integer t (1 ≤ t ≤ 1000) — the number of test cases.
The first and only line of each test case contains three integers r, b, and d (1 ≤ r, b ≤ 10^9; 0 ≤ d ≤ 10^9) — the number of red and blue beans and the maximum absolute difference in each packet.
Output
For each test case, if you can distribute all beans, print YES. Otherwise, print NO.
You may print every letter in any case you want (so, for example, the strings yEs, yes, Yes and YES are all recognized as positive answer).
Example
Input
4
1 1 0
2 7 3
6 1 4
5 4 0
Output
YES
YES
NO
NO
Note
In the first test case, you can form one packet with 1 red and 1 blue bean. The absolute difference |1 - 1| = 0 ≤ d.
In the second test case, you can form two packets: 1 red and 4 blue beans in the first packet and 1 red and 3 blue beans in the second one.
In the third test case, since b = 1, you can form only one packet with 6 red and 1 blue beans. The absolute difference |6 - 1| = 5 > d.
In the fourth test case, since d = 0 so each packet should contain the same number of red and blue beans, but r ≠ b.

Sereja and his friends went to a picnic. The guys had n soda bottles just for it. Sereja forgot the bottle opener as usual, so the guys had to come up with another way to open bottles.
Sereja knows that the i-th bottle is from brand ai, besides, you can use it to open other bottles of brand bi. You can use one bottle to open multiple other bottles. Sereja can open bottle with opened bottle or closed bottle.
Knowing this, Sereja wants to find out the number of bottles they've got that they won't be able to open in any way. Help him and find this number.
Input
The first line contains integer n (1 ≤ n ≤ 100) — the number of bottles. The next n lines contain the bottles' description. The i-th line contains two integers ai, bi (1 ≤ ai, bi ≤ 1000) — the description of the i-th bottle.

A professor invented Cookie Breeding Machine for his students who like cookies very much.
When one cookie with the taste of x is put into the machine and a non-negative integer y less than or equal to 127 is input on the machine, it consumes the cookie and generates two cookies with the taste of y and (x XOR y).
Here, XOR represents Bitwise Exclusive OR.
At first, there is only one cookie and the taste of it is D .
Find the maximum value of the sum of the taste of the exactly N cookies generated after the following operation is conducted N-1 times.

Problem
One day, Kawabayashi is about to have lunch at the school cafeteria. There are three types of daily lunch menus for school cafeterias: A lunch, B lunch, and C lunch.
Kawabayashi is a glutton, so I would like to eat all three types of daily lunch menus one by one.
However, Kawabayashi decided to put up with one type of lunch menu and eat two different types of lunch menus so as to minimize the total calorie intake with care for his health.
Ask for a lunch menu that Kawabayashi will endure when given the calories of A, B, and C lunches one day.
Constraints
The input satisfies the following conditions.
* $ 1 \ leq a, b, c \ leq 5000 $
* $ a \ neq b, b \ neq c, c \ neq a $
Input
The input is given in the following format.
$ a $ $ b $ $ c $
Three integers $ a $, $ b $, $ c $ are given, separated by spaces. Each represents the calories of A lunch, B lunch, and C lunch one day.
Output
Output the menu name that Kawabayashi will endure on one line.
"A" to put up with A lunch
"B" to put up with B lunch
"C" to put up with C lunch
Output.
