Total Expenses Calculation

You are given multiple test cases. In each test case, you are provided with an integer N representing the number of friends and a list of N integers representing each friend's contribution. Your task is to calculate the total expense for each group.

The total expense for a group can be expressed mathematically as: \( S = \sum_{i=1}^{N} a_i \), where \( a_i \) is the contribution of the \( i^{th} \) friend.

Print the result for each test case on a separate line.

inputFormat

The first line of the input contains a single integer T (the number of test cases). Each test case is described as follows:

• The first line of each test case contains an integer N, the number of friends.
• The second line contains N space-separated integers, representing the contributions of the friends.

All input should be read from standard input (stdin).

outputFormat

For each test case, output a single line containing the total sum of the contributions for that group. The output should be written to standard output (stdout).
