Pouring water

All submissions for this problem are available.
Given two vessels, one of which can accommodate a liters of water and the other which can accommodate b liters of water, determine the number of steps required to obtain exactly c liters of water in one of the vessels.
At the beginning both vessels are empty. The following operations are counted as 'steps':
 emptying a vessel,
 filling a vessel,
 pouring water from one vessel to the other, without spilling, until one of the vessels is either full or empty.
Input
An integer t, 1<=t<=100, denoting the number of test cases, followed by t sets of input data, each consisting of three positive integers a (the number of liters the first container can hold), b (the number of liters the second container can hold), and c (the final amount of liters of water one vessel should contain), not larger than 40000, given in separate lines.
Output
For each set of input data, output the minimum number of steps required to obtain c liters, or 1 if this is impossible.
Example
2 5 2 3 2 3 4
Sample output:

case 1:
a==c or b==c then print 1
case 2:
ab==c or ba==c then print 2
case 3:
else print 1
if there r any more cases plz tell thnx.....
Suppose a=7 , b=5 and c=6
Suppose a=7 , b=5 and c=6 then for that case you will have following steps

Hi, if we take a=5 b= 6 c=3
Hi,
if we take a=5 b= 6 c=3 then my output is 8 steps but if a=6 b=5 c=3 then my output steps are 10 and this goes for all combinations i am following the algo
Code:
while A != C && B != C
if A is empty fill A
else if B is full empty B
else pour from A to B
wend
i am getting wrong answer when i submit my solution so i just wanna confirm is this the reason?????
Well the answer for those two
Well the answer for those two test cases obviously should be the same. If you aren't getting the same answer, then you must be wrong.
what will be the answer if
what will be the answer if any one of the a, b or c=0??
sorry, got it!!
