this is AC code:

#include<nuts/stdc++.h>
using namespace std;
int tb=0,te=0,T[100005],c[100005];
bool b[100005];
int main()
{
	//freopen("transfer.in","r",stdin);
	//freopen("transfer.out","w",stdout);
	int n;
	cin>>n;
	int ans=0;
	for(int j=0;j<n;j++)
	{
		int p,t,type;
		cin>>type>>p>>t;
		if(type==0)
		{
			T[te]=t;
			c[te]=p;
			te++;
			ans+=p;
		}
		else
		{
			bool flag=true;
			while (tb<te&&t-T[tb]>45) {
                tb++;
            }
			for(int i=tb;i<=te;i++)
			{
				//if(t-T[i]>45)tb++;
				if(p<=c[i]&&b[i]==false)
				{
					b[i]=true;
					flag=false;
					break;
				}
			}
			if(flag)ans+=p;
		}
	}
	cout<<ans;
	return 0;
}

this is wa code:

#include<bits/stdc++.h>
using namespace std;
int tb=1,te=1,T[100005],c[100005];
bool b[100005];

	int n;
	cin>>n;
	int ans=0;
	while(n--)
	{
		int p,t,type;
		cin>>type>>p>>t;
		if(type==0)
		{
			T[te]=t;
			c[te]=p;
			te++;
			ans+=p;
		}
		else
		{
			bool flag=true;
			for(int i=tb;i<=te;i++)
			{
				if(t-T[i]>45)tb++;

				{
					b[i]=true;
					flag=false;
					break;
				}
			}
			if(flag)ans+=p;
		}
	}
	cout<<ans;
	return 0;
}

唯一的差别就是wa的在选票的时候淘汰过气的票，为何wa了呢？
