SPEED  Circular Track
Two persons are running on a circular track either in the same direction or in the opposite direction, indefinitely. The speed of both of them is given to you. Speed will be positive in clockwise direction, and negative in anticlockwise direction. Print the number of distinct points, at which they will meet on the circle.
Input
First line contains T, number of test cases. Each test case contains two integers, S1 and S2 (not equal to zero) which are the speeds of the two persons. S1 and S2 will be distinct.
Edited: All the numbers fit in signed 32bit integer.
Output
Print in a separate line, the number of distinct points at which they meet.
Example
Input 2 1 2 1 1 Output 1 2

Those getting WA check that when both s1 and s2 is negative then they are in same direction
