拼多多第一题通过率0%，我真找不出来是为什么了SOS

求佬帮忙看一下，给定的示例倒是都过了_(:з」∠)_
#include
# include 
using namespace std;

int main() {
    int T;
    cin>>T;
    vector H(T);
    vector N(T);
    vector>> time(T,vector>());
    for(int i=0;i>H[i];
        cin>>N[i];
        long firstval,secondval;
        for(int j=0;j>firstval>>secondval;
            time[i].push_back(make_pair(firstval,secondval));
            // cin>>time[i][j].first>>time[i][j].second;
        }
    }

    for(int i=0;i> cur_time;
        for(int m=0;mright){
                cur_time.push_back(make_pair(left,right));
                left=time[i][j].first;
                right=time[i][j].second;
            }
            if(time[i][j].firstleft){
                left=time[i][j].first;
            }
            if(time[i][j].second>right&&time[i][j].first> a >> b) { // 注意 while 处理多个 case
    //     cout << a + b << endl;
    // }
}
// 64 位输出请用 printf("%lld")
