心烦意乱，输出不同的结果发泄下。。。。

题目来源：http://acm.hdu.edu.cn/showproblem.php?pid=1089 1089替换为[1089,1096]即可。

code：

/*1089*/#include <iostream>#include <cstdio>using namespace std;int a,b;int main(){    while(scanf("%d%d",&a,&b)!=EOF)          printf("%d\n",a+b);    return 0;}/*1090*/#include <iostream>#include <cstdio>using namespace std;int n,a,b;int main(){    scanf("%d",&n);    while(n--){        scanf("%d%d",&a,&b);        printf("%d\n",a+b);    }    return 0;}/*1091*/#include <iostream>#include <cstdio>using namespace std;int a,b;int main(){    while(scanf("%d%d",&a,&b)!=EOF && (a||b))        printf("%d\n",a+b);    return 0;}/*1092*/#include <iostream>#include <cstdio>using namespace std;int n,sum,num;int main(){    while(scanf("%d",&n)!=EOF && n){        sum=0;        for(int i=0;i<n;i++){            scanf("%d",&num);            sum+=num;        }        printf("%d\n",sum);    }    return 0;}/*1093*/#include <iostream>#include <cstdio>using namespace std;int n,m,sum,num;int main(){    scanf("%d",&n);    while(n--){        scanf("%d",&m);        sum=0;        for(int i=0;i<m;i++){            scanf("%d",&num);            sum+=num;        }        printf("%d\n",sum);    }    return 0;}/*1094*/#include <iostream>#include <cstdio>using namespace std;int n,sum,num;int main(){    while(scanf("%d",&n)!=EOF){        sum=0;        for(int i=0;i<n;i++){            scanf("%d",&num);            sum+=num;        }        printf("%d\n",sum);    }    return 0;}/*1095*/#include <iostream>#include <cstdio>using namespace std;int a,b;int main(){    while(scanf("%d%d",&a,&b)!=EOF)          printf("%d\n\n",a+b);    return 0;}/*1096*/#include <iostream>#include <cstdio>using namespace std;int n,m,sum,num;int main(){    scanf("%d",&n);    while(n--){        scanf("%d",&m);        sum=0;        for(int i=0;i<m;i++){            scanf("%d",&num);            sum+=num;        }        if(n!=0) printf("%d\n\n",sum);        else printf("%d\n",sum);    }    return 0;}
