Problem of the day
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

In the first test case, the answer is 10 because all integers between 1 and 4 are 1, 2, 3, and 4. Hence 1 + 2 + 3 + 4 is equal to 10.
In the second test case, the answer is 25 because all integers between 1 and 4 are 1, 2, 3, and 4. Hence 1 * 2 * 3 * 4 is equal to 24.
