$P$ passengers are travelling and they have a total of $Q$ tickets. Help Chef calculate the total fine collected.

Input Format

The first line contains a single integer $T$ , the number of test cases. $T$ lines follow. Each following line contains three integers separated by spaces, whose description follows.

The first integer, $X$ , is the fee in rupees.
The second integer, $P$ , is the number of passengers on the train.
The third integer, $Q$ , is the number of tickets Chef collected.

Output Format

The $i^{th}$ line must contain a single integer, the total money(in rupees) collected by Chef corresponding to the $i^{th}$ test case.

Constraints

Input

Output

Explanation:

Test case $1$ : The total number of passengers travelling without ticket are $1 - 1 = 0$ . So the total fine collected is $\cdot 4 = 0$ rupees.

Test case $2$ : The total number of passengers travelling without ticket are $10 - 7 = 3$ . So the total fine collected is $\cdot 2 = 6$ rupees.

Test case $3$ : The total number of passengers travelling without ticket are $5 - 4 = 1$ . So the total fine collected is $\cdot 8 = 8$ rupees.

Test case $4$ : The total number of passengers travelling without ticket are $7 - 0 = 7$ . So the total fine collected is $\cdot 9 = 63$ rupees.
