First N

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.

Sample Input 2 :

2
1
4

Sample output 2 :
