According to a recent survey, Biryani is the most ordered food. Chef wants to learn how to make world-class Biryani from a MasterChef. Chef will be required to attend the MasterChef's classes for X weeks, and the cost of classes per week is Y coins. What is the total amount of money that Chef will have to pay?

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

- The first line of input will contain an integer T — the number of test cases. The description of T test cases follows.
- The first and only line of each test case contains two space-separated integers X and Y, as described in the problem statement. 

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

For each test case, output on a new line the total amount of money that Chef will have to pay. 

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

$1 ≤ T ≤ 10^{4}$
$1 ≤ X, Y ≤ 100$

----- Sample Input 1 ------ 
4
1 10
1 15
2 10
2 15
----- Sample Output 1 ------ 
10
15
20
30

----- explanation 1 ------ 
Test case $1$: Chef will be required to attend the MasterChef's classes for $1$ week and the cost of classes per week is $10$ coins. Hence, Chef will have to pay $10$ coins in total.

Test case $2$: Chef will be required to attend the MasterChef's classes for $1$ week and the cost of classes per week is $15$ coins. Hence, Chef will have to pay $15$ coins in total.

Test case $3$: Chef will be required to attend the MasterChef's classes for $2$ weeks and the cost of classes per week is $10$ coins. Hence, Chef will have to pay $20$ coins in total.

Test case $4$: Chef will be required to attend the MasterChef's classes for $2$ weeks and the cost of classes per week is $15$ coins. Hence, Chef will have to pay $30$ coins in total.
