Difficulty: Easy

```
Given ‘N’ = 4, ‘Q’ = 1.
Then the answer is 10 because the sum of all integers between 1 and 4 are 1, 2, 3, and 4. Hence 1 + 2 + 3 + 4 is equal to 10.
```

```
The first line of input contains an integer ‘T’ denoting the number of test cases.
Next, ‘T’ lines contain two space-separated integers ‘N’, where ‘N’ is the number given and ‘Q’, denoting the type of query.
```

```
For each test case, You are supposed to return an integer denoting the sum or product of ‘N’ numbers.
```

```
You are not required to print the expected output; it has already been taken care of. Just implement the function.
```

```
1 <= ‘T’ <= 10
1 <= ‘N’ <= 10^4
1 <= ‘Q’ <= 2
Time Limit: 1 sec.
