A+B for Input-Output Practice (VIII)
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
4 1 2 3 4
5 1 2 3 4 5
3 1 2 3
Sample Output
10
15

public class Main {
public static void main(String[] args) {

int n=sc.nextInt();
boolean boo=true;
while(n-->0){
int m=sc.nextInt();
int sum=0;
for(int i=0;i<m;i++){
int a=sc.nextInt();
sum+=a;
}
if(boo){
boo=false;
}else{
System.out.println();
}
System.out.println(sum);
}
}
