Problem Statement

#### You are given a positive integer ‘N’. You have to find the sum of first ‘N’ natural numbers.

##### For Example:
``````If N = 3.
Sum of the first 3 natural numbers will be 1 + 2 + 3 = 6. Hence, the output will be 6.
``````
##### Input Format :
``````The first line of the input contains an integer, 'T’, denoting the number of test cases.

The first line of each test case contains a single positive integer ‘N’.
``````
##### Output Format :
``````For each test case, print the sum of first ‘N’ natural numbers.

Print a separate line for each test case.
``````
##### Note :
``````You do not need to print anything, it has already been taken care of. Just implement the given function.
``````
##### Constraints :
``````1 <= T <= 10
1 <= N <= 10^6

Time limit: 1 sec
``````
##### Sample Input 1 :
``````2
3
2
``````
##### Sample output 1 :
``````6
3
``````
##### Explanation For Sample Output 1 :
``````For the first test case,
N = 3.
Sum of the first 3 natural numbers will be 1 + 2 + 3 = 6. Hence, the output will be 6.

For the second test case,
N = 2.
Sum of the first 2 natural numbers will be 1 + 2 = 3. Hence, the output will be 3.
