Harsh was recently gifted a book consisting of *N* pages. Each page contains exactly *M* words printed on it. As he was bored, he decided to count the number of words in the book.

Help Harsh find the total number of words in the book.

- The first line of input will contain a single integer
*T*, denoting the number of test cases. - Each test case consists of two space-separated integers on a single line,
*N*and*M*— the number of pages and the number of words on each page, respectively.

For each test case, output on a new line, the total number of words in the book.

- 1 \leq T \leq 1001≤
*T*≤100 - 1 \leq N \leq 1001≤
*N*≤100 - 1 \leq M \leq 1001≤
*M*≤100

```
Input: 4
1 1
4 2
2 4
95 42
Output: 1
8
8
3990
```

**Test case 1:** The book consists of only 1 page, and each page has only 1 word. Hence, the total number of words is 1.

**Test case 2:** The book consists of 4 pages, and each page has 2 words. Hence, the total number of words is 2+2+2+2=8.

**Test case 3:** The book consists of 2 pages, and each page has 4 words. Hence, the total number of words is 4+4=8.

**Test case 4:** The book consists of 95 pages, and each page has 42 words. Hence, the total number of words is 3990.
