//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.

// 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, in a separate line.

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

// Constraints :

// 1 <= t <= 10^2

// 0 <= N <= 10^6

// 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
