You are the principal of the Cake school in chefland and today is your birthday. You want to treat each of the children with a small cupcake which is made by you. But there is a problem, You don't know how many students are present today.
The students have gathered of the morning assembly in $R$ rows and $C$ columns. Now you have to calculate how many cakes you have to make such that each child gets a cupcake. 

-----Input:-----
- First-line will contain $T$, the number of test cases. Then the test cases follow. 
- Each test case contains a single line of input, two integers $R$ and $C$. 

-----Output:-----
For each test case, output number of cupcakes you have to make.

-----Constraints-----
- $1 \leq T \leq 1000$
- $2 \leq R,C \leq 10^6$

-----Sample Input:-----
1
5 10

-----Sample Output:-----
50
