SPOJ Problem Set (classical)
13388. Easy Jug
Problem code: MAY99_3
One day Manku was very thirsty , so he decided to drink exactly z litres of water .
However , in front of him, there is a well of infinite amount of water and 2 empty jugs of quantity x litres and y litres respectively.
Now Manku can do the following operations to any jug
1> Fill it completely from the well
2> Empty it entirely
3> Transfer as much water from Jug 1 to Jug 2 , till Jug 1 gets empty or Jug 2 is completely filled.
Now since he has no measuring device so he will do these operations only to make any of the 2 jug having exactly z litres of water.
Now Your task is given value of x,y,z , tell whether it is possible for Manku to drink water or not.
First Line of Input contains t , no. of test cases. (t<=25)
Then for each test case there are 3 no's x,y,z given in separate line
For each test case output "YES" if manku can drink exactly z litres of water else "NO".

In Test case 1 Either Manku can have 2 or 4 litres of water so he cant drink 3 litres
In Test case 2 Manku can have 1 litre water by doing the following operations
-> Fill 2 litre Jug
-> Transfer its water to 5 litre Jug
-> Again Fill 2 litre Jug
-> Again Transfer its entire water to 5 litre Jug
Now 5 litre Jug will have total 4 litre water
->Again Fill 2 litre Jug
-> Now transfer 1 litre water to 5 litre Jug
because at present 5 litre Jug don't have space for more than 1 litre water
Now the 2 litre Jug will have only 1 litre water left
For Test case 3 we will transfer 3 litre water twice from 3 litre jug to 9 litre jug
For test Case 4 , transfer 3 times water of 3 litre jug to 8 litre jug
Ultimately 3 litre Jug has 1 litre water left and 8 litre Jug is full
Now empty 8 litre jug and pour remaining 1 litre of 3 litre jug in it
Now fill 3 litre jug fully twice and transfer its water to 8 litre jug
Now 8 litre Jug will have 7 litre water
For Test case 5, we cant have 10 litre of water in any jug
