Problem Statement

We have $N$ chairs arranged in a circle, one of which is a throne.

Takahashi is initially sitting on the chair that is $S$ chairs away from the throne in the clockwise direction. Now, he will repeat the move below.

Move: Go to the chair that is $K$ chairs away from the chair he is currently sitting on in the clockwise direction.

After how many moves will he be sitting on the throne for the first time? If he is never going to sit on it, report -1 instead.

You are asked to solve $T$ test cases.

Constraints

• $1\leq T \leq 100$
• $2\leq N \leq 10^9$
• $1\leq S < N$
• $1\leq K \leq 10^9$
