Problem

Sang-geun is the CEO of TGN. TGN looks like it stands for Teenager Game Network, but it actually stands for Temporary Group Name.

The company builds apps for teenagers. After a full year of development the app is finally finished, and all that is left is to sell it.

Sang-geun spends an enormous amount on dates, so he wants to maximize his revenue by advertising wisely. One day he gained the ability to predict, in advance, the effect of an advertisement.

For each app you are given the revenue without advertising, the revenue with advertising, and the advertising cost. Write a program that decides whether advertising is worth it.

The final revenue when advertising is (revenue with advertising) $-$ (advertising cost). If this value is greater than the revenue without advertising, advertise; if it is smaller, do not advertise; if they are equal, it does not matter.

Input

The first line contains the number of test cases $N$ . Each of the next $N$ lines contains three integers $r$ , $e$ , and $c$ , where $r$ is the revenue without advertising, $e$ is the revenue with advertising, and $c$ is the advertising cost. ( $-10^6 \le r, e \le 10^6$ , $0 \le c \le 10^6$ )

Output

For each test case, print a single line: advertise if advertising is worth it, do not advertise if it is not, and does not matter if advertising makes no difference to the revenue.
