The *fuel economy* of a car is the distance which it can travel on one litre of fuel.

The base fuel economy (i.e, its fuel economy when there is only one person - the driver - in the car) of a certain car is M kilometres per litre. It was also observed that every extra passenger in the car *decreases* the fuel economy by 1 kilometre per litre.

P people want to take this car for a journey. They know that the car currently has V litres of fuel in its tank.

What is the maximum distance this car can travel under the given conditions, assuming that all P people always stay in the car and no refuelling can be done?

Note that among the P people is also a driver, i.e, there are exactly P people in the car.

------ Input Format ------ 

- The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follows.
- Each test case consists of a single line of input, containing three space-separated integers P, M, and V - the number of people, base fuel economy, and amount of fuel present in the car, respectively.

------ Output Format ------ 

For each test case, output a single line containing one integer - the maximum distance that the car can travel.

------ Constraints ------ 

$1 ≤ T ≤ 3 \cdot 10^{4}$
$1 ≤ P ≤ 5$
$6 ≤ M ≤ 56$
$1 ≤ V ≤ 100$

Test Case $1$: 
There are $5$ people in the car, and its base fuel economy is $10$. Thus, its effective fuel economy is $10 - 4 = 6$, since there are $4$ people present other than the driver.
There are $20$ litres of fuel in the car, so the maximum distance that can be travelled is $6\cdot 20 = 120$.

Test Case $2$: 
The effective fuel economy is $6$, and the maximum distance that can be travelled is $6\cdot 10 = 60$.

Test Case $3$: 
The effective fuel economy is $3$, and the maximum distance that can be travelled is $3\cdot 1 = 3$.
