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: $1 \le n \le 100$, $-10^{6} \leq r,e \leq 10^{6}$ and $0 \leq c \leq 10^{6}$.
Output one line for each test case: “advertise”, “do not advertise” or “does not matter”, indicating whether it is most profitable to advertise or not, or whether it does not make any difference.
