实例：
#include <iostream>#include <vector>#include <string>using namespace std;int main(){ int t; cin>>t; while(t--){ int n; cin>>n; string s; cin>>s; int l = -1; for(int j=0; j<s.size(); j++) { if(s[j] == '8') { l = j; break; } } if(l == -1) { cout<<"NO"<<endl; continue; } else if(s.size()-l < 11) { cout<<"NO"<<endl; continue; } else { cout<<"YES"<<endl; continue; } } return 0;} 题目4： 题目描述
