// Return Array Sum

// Given an array/list(ARR)of length N,you need to find and return the sum of all the elements in the array/list.

// Input Format:

// The first line contains an Integer't'which denotes the number of test cases or queries to be run.Then the test cases follow.

// The first line of each test case or query contains an integer'N'representing the size of the array/list.

// Second line contains'N'single space separated integers representing the elements in the array/list.

// Output Format:

// For each test case,print the sum of the numbers in the array/list.

// Output for every test case will be printed in a separate line.

// Constraints:

// 1<=t<=10^2

// 0<=N<=10^5

// Time Limit:1 sec

// Sample Input 1:

// 1 3 9 8 9

// Sample Output 1:

// 26

// Sample Input 2:

// 2

// 5 1 2 3 4

// 5 3 10 20 30

// Sample Output 2:

// 15

// 60
