代码如下：

#include <iostream>
using namespace std;
struct youhui{
	long long time,price;
	bool have;
}a[1000];
long long alen=-1;
bool afind(long long p,long long q)					//p是价格，q是时间 
{
	for(int i=0;i<=alen;i++)
	{
		if(a[i].have)
		if(q-a[i].time<=45)
		if(p<=a[i].price)
		{a[i].have=false;
		return true;}
	}
	return false;
}
int main()
{
	long long money=0;
//	freopen("transfer.in","r",stdin);
//	freopen("transfer.out","w",stdout);
	int n;
	cin>>n;
	int d,b,c;
	for(int i=0;i<n;i++)
	{
		cin>>d>>b>>c;
		if(d==0)
		{
			money+=b;
			alen++;
			a[alen].price=b;
			a[alen].time=c;
			a[alen].have=true;
		}else
		if(!afind(b,c))money+=b;
	}
	cout<<money;
//	fclose(stdin);
//	fclose(stdout);
	return 0;
}
