Gather sand to form a tower is a Chinese idiom, whose Pinyin is $j\grave{u}\ sh\bar{a}\ ch\acute{e}ng\ t\check{a}$. It means to pile sand into a pagoda, referring that a little makes a lot. From the fahua Sutra - convenience products.

Suppose the tower has $N$ floors. There are $i\times i$ rooms on the $i^\text{th}$ floor. Each room can accommodate $M$ people. How many people can the $N$ floor tower accommodate?

## Input:

The first line is a positive integer $T\ (1 \le T \le 100)$, indicating that there are $T$ test data.

Next, there are $T$ lines. Each line has two positive integers $N$ and $M\ (1 \le N,M \le 100)$, indicating the number of floors of the tower and the number of people that can be accommodated in each room in a test data.

## Output:

Each test data outputs a line containing one positive integer, that is, the total number of people that can be accommodated in the $N$ floor tower.
