Given an array of N integers. My task is to print the sum of all of the integers.

Input:

First line of input file contains a single integer T which denotes the number of test cases. For each test case, there will be two lines. First line contains N which denotes number of elements in an array, and second line contains N space seperated integers.

Output:

Corresponding to each test case, print the sum of array in a new line.

Constraints:

1 <= T <= 100

1 <= N <= 1000

0 <= Arr[i] <= 200

```
#include <iostream>
using namespace std;
int main()
{
int n, no_of_elem_array;
int arr[50], sum[50];
cin >> n;
int j = 0;
while (n--) {
cin >> no_of_elem_array;
for (int i = 0; i < no_of_elem_array; i++) {
cin >> arr[i];
}
for (int i = 0; i < no_of_elem_array; i++) {
sum[j] = sum[j] + arr[i];
}
j++;
}
for (int i = 0; i < n; i++) {
cout << sum[i] << endl;
}
return 0;
}
```

**Output**
