Problem Description

You are the CEO of Nasty Hacks Inc., a company that creates small pieces of malicious software which teenagers may use
to
fool their friends. The company has just finished their first product
and it is time to sell it. You want to make as much money as possible
and consider advertising in order to increase sales. You get an analyst
to predict the expected revenue, both with and without advertising. You
now want to make a decision as to whether you should advertise or not,
given the expected revenues.

 

Input

The input consists of n cases, and the first line consists of one
positive integer giving n. The next n lines each contain 3 integers, r,
e and c. The first, r, is the expected revenue if you do not advertise,
the second, e, is the expected revenue if you do advertise, and the
third, c, is the cost of advertising. You can assume that the input will
follow these restrictions: -10⁶ ≤ r, e ≤ 10⁶ and 0 ≤ c ≤ 10⁶.

 

Output

Output one line for each test case: “advertise”, “do not
advertise” or “does not matter”, presenting whether it is most
profitable to advertise or not, or whether it does not make any
difference.

 

Sample Input
