rt，代码如下：

#include<bits/stdc++.h>
using namespace std;
#define qwq return 0;
int time,time2,ti,ans,n,monny;
int main(){
	cin>>n;
	for(int i=0;i<n;i++){
		cin>>ti>>monny>>time;
		if(ti==0){
			time2=time;
			ans+=monny;
			continue;
		}else if(ti==1){
			if(!time2){
				ans+=monny;
			}else{
				if(time2-time<=45){
					continue;
				}else{
					ans+=monny;
				}
			}
		}
	}
	cout<<ans<<"\n";
	qwq
}

求调（脑子抽了)
