题目大意:

    公交车有n行,每行有2个座位,每一行的座位大小都为w[i],现在有两种人,第一种会先坐空行的位子,再在空
行里面选择最大w[i]的位子坐;第二种人则是选择有人坐的一行,在那些行里选择位子w[i]最小的

分析:

先将位子按w排序,第一种人选定好后,将他的座位放入队列里,然后第二种人从队列里选择w最小的就行了

code:

#define debug
#include<bits/stdc++.h>
#define pb push_back
#define dbg(x) cout<<#x<<" = "<<(x)<<endl;
#define lson l,m,rt<<1
#define cmm(x) cout<<"("<<(x)<<")";
#define rson m+1,r,rt<<1|1
using namespace std;
typedef long long ll;
typedef pair<int,int> pii;
typedef pair<ll,ll>PLL;
typedef pair<int,ll>Pil;
const ll INF = 0x3f3f3f3f;
const ll inf=0x7fffffff;
const double eps=1e-8;
const int maxn =1e6+10;
const int N = 510;
const ll mod=1e9+7;
const ll MOD=1e9;
//------
//define
int a[maxn];
struct node{
	int id,w;
	node(int id=0,int w=0):id(id),w(w){}
	bool operator <(const node &a)const{
		return w<a.w;
	}
}w[maxn]; 
//solve
void solve() {
	int n;
	while(cin>>n){
		int cnt_1=0;
		int cnt_2=n-1;
		priority_queue<node>q;
		for(int i=0;i<n;i++){
			int tmp;
			cin>>tmp;
			w[i]=node(i+1,tmp);
		}
		sort(w,w+n);
		for(int i=0;i<2*n;i++){
			char tt;
			cin>>tt;
			int tmp=tt-'0';
			if(!tmp){
				a[i]=w[cnt_1].id;
				q.push(w[cnt_1++]);
				
			}else{
				a[i]=q.top().id;
				q.pop();
			}
		}
		for(int i=0;i<2*n;i++){
			cout<<a[i]<<" ";
		}
	}
}

int main() {
	ios_base::sync_with_stdio(false);
#ifdef debug
	freopen("in.txt", "r", stdin);
//	freopen("out.txt","w",stdout);
#endif
	cin.tie(0);
	cout.tie(0);
	solve();
	/*
		#ifdef debug
			fclose(stdin);
			fclose(stdout);
			system("out.txt");
		#endif
	*/
	return 0;
}
