All submissions for this problem are available.Chef is studying Rotational Motion in physics. Here is preparing for Engineering Entrance exam. He's stuck in a problem. Which states that "Two fans, each with a single blade are rotating one above the other, about the same axis of rotation and both blades have the same length. Consider the blade as a rod. Both the fans are rotating indefinitely. 


Fans can rotate in either **clockwise** or **anticlockwise** direction. There is a dot marked on the blade of both the fans and the dot is marked at the same distance from the center of rotation.
You're be given speeds of the fans. />/>

3. Clockwise rotation - positive speed.
4. Anticlockwise rotation - negative speed.


Help Chef to find the number of distinct points the dots will coincide on the circumference of rotation. />

### Input

First line consists of **T** Test cases.
Each of the next **T** lines consists of Two numbers **S1** and **S2** which describes the speed of rotation of both the fans respectively

### Output

Print **T** lines with each containing the required answer.

### Constraints

11. 1 ≤ **T** ≤ 100
12. **S1** ≠ **S2**
13. **S1,S2** ≠ 0
14. -100000 ≤ **S1,S2** ≤ 100000.
