int main()

    int count,i;
    long long sum=0,aray[25];
    cin>>count;
    for(i=0;i<count;i++)
    {
        cin>>aray[i];
        sum+=aray[i];
    }
    cout<<sum;

    return 0;
}

Take long long as data type as it will save value 10^10 times that means A[i] value can be 1000000000

        if(sum!=0)
            System.out.println(sum);
        else
            System.out.println();
    }
}
