HDU1003最大连续子序列和

很惭愧，一开始定义最大值为0，WA了好几次，最后把最大值初始为-1001，才AC。

还是不能大意。

#include <iostream>
using namespace std;
int main(){
    //freopen("in.txt","r",stdin);
    int T;
    cin>>T;
    int num =1;
    while(T--){
        int n;
        cin>>n;
        int i,a;
        long long  maxsum = -1001;
        int start=0,end=0;
        long long tempsum = 0;
        int tempstart = 1;
        for(i=0;i<n;i++){
            cin>>a;
            tempsum = tempsum + a;
            if(tempsum>maxsum){
                maxsum = tempsum;
                start = tempstart;
                end = i+1;
            }
            if(tempsum<0){
                tempsum = 0;
                tempstart = i+2;
            }
        } 
        cout<<"Case "<<num++<<":"<<endl;
        cout<<maxsum<<" "<<start<<" "<<end<<endl;
        if(T) cout<<endl;
    } 
    return 0;
}
