Water n Jugs

In the movie Die Hard 3, our heros, John McClain (Bruce Willis) and Zeus (Samuel L. Jackson), are at the bidding of the evil Peter Krieg (Jeremy Irons). First they are sent to the pay phone, then to the subway, and finally to the park. There is a fountain in the park. It is here that they must make exactly c gallons from a and b gallon jugs. It should be assumed that there is infinite supply of water from the fountain.

They are under much pressure. You have to help them determine if it is even possible to make exactly c gallons from a and b gallon jugs. If c liters of water is measurable, you must have c liters of water contained within one or both jugs by the end.

You are allowed to do the following things.

1. Fill any of the jugs completely with water.

2. Empty any of the jugs.

3. Pour water from one jug into another till the other jug is completely full or the first jug itself is empty.

Input Format:
First line of input contains an integer t, representing the number of test cases.
Next t lines follow input of 3 space separated integers a,b and c respectively.
1 <= t <= 3*10^5 
1 <= a <= 10^4 
1 <= b <= 10^4 
1 <= c <= 10^4 
Time Limit: 1 second
Output Format:
For each query, you have to print “Yes” if it is possible to make exactly c gallons from a and b gallon jugs, otherwise print “No”.
Sample Input 1:
3 5 4
Sample Output 1:
First, fill the 2nd jug with 5 litres and pour it into the 3 litres jug. Now 2 litres will be there in the 5-litre jug. Empty the 3-litre jug and pour 2 litres of the other jug into the 3-litre jug. Now again fill the 5-litre jug. 
Now completely fill the 3-litre jug with the 5-litre jug, leaving with 4 litres in the 5-litre jug.
Sample Input 2:
6 3 4
10 18 12
20 25 10
Sample Output 2:


import math

while t>0:
    if((a+b>=c ) ):
