求助

这里是代码

#include<iostream>
#include<cstdio>
#define ll long long
using namespace std;
ll n,s=0,price,time,front=0,back=0;
bool isbus;
struct ticket{
	ll price,time;
	bool check(ll p,ll t){
		return p<=price && (t-time)<=45;
	}
}a[100001];

int main(){
	cin>>n;
	for(int i=1;i<=n;++i){
		cin>>isbus>>price>>time;
		if(isbus){
			bool isfound = false;
			for(int j=back;j<front;++j){
				if( a[j].check(price,time) ){
					back++;
					isfound = true;
					break;
				}
			}
			if(!isfound){
				s+=price;
			}
		}else{//subway
			s+=price;
			a[front].price = price;
			a[front].time = time;
			front++;
		}
	}
	cout<<s;
    return 0;
}

这里是报错信息
