Problem Description
Your task is to calculate the sum of some integers.
Input
Input contains an integer N in the first line, and then N lines follow. Each line starts with a integer M, and then M integers follow in the same line.
Output
For each group of input integers you should output their sum in one line, and you must note that there is a blank line between outputs.
Sample Input
3

5 1 2 3 4 5
3 1 2 3
Sample Output
10
15
6
import java.util.*; class Main{ public static void main(String args[]){ Scanner sc = new Scanner(System.in); boolean isFirst = true; int m=sc.nextInt(); while(m-->0){ int n=sc.nextInt(); int sum=0; for(int i=0;i<n;i++){ int a=sc.nextInt(); sum+=a; } if(isFirst){ isFirst=false; }else{ System.out.println(); } System.out.println(sum); } } }
