神啊，我是否還可獲得救贖

  兩個月之後，我再刷起了題，才發覺是多麼力不從心，完全沒有了以前的感覺，就好似回到了初學那個年代

這麼水的題我竟………………不說，太丟臉了

     

#include<iostream>#include<stack>#include<string>#include<vector>using namespace std;int main(){stack<char> sta;string a,b;vector<bool> ans;int num;while(cin>> num){    cin >>a >>b;string::size_type i = 0;string::size_type j = 0;for(; i != a.size(); i++){sta.push(a[i]);ans.push_back(true);while(sta.size() && j != b.size()){if(sta.top() == b[j]){sta.pop();ans.push_back(false);j++;}else break;}if(j == b.size())break;}if(ans.size() == num*2){cout <<"Yes." <<endl;for(vector<bool>::size_type i = 0;i != ans.size();i++){if(ans[i])cout <<"in" <<endl;elsecout <<"out" <<endl;}}elsecout <<"No." <<endl;cout <<"FINISH" <<endl;

ans.clear();while(sta.size())sta.pop();}return 0;}
