@YMS2333 每次操作完要清空栈

@YMS2333 加的：

#include<iostream>
#include<vector>
using namespace std;
int main()
{
    vector<unsigned long long> v;
    int t;
    cin>>t;
    string caozuo;
    unsigned long long temp;
    while(t--)
    {
        int n;
        cin>>n;
        v.clear();  //clear
        for(int i=0;i<n;++i)
        {
            cin>>caozuo;
            if(caozuo=="push")
            {
                cin>>temp;
                v.push_back(temp);
            }
            if(caozuo=="pop")
            {
                if(v.size()!=0)
                    v.pop_back();
                else
                    cout<<"Empty"<<endl;
            }
            if(caozuo=="query")
            {
                if(v.size()!=0)
                    cout<<v.back()<<endl;
                else
                    cout<<"Anguei!"<<endl;
            }
            if(caozuo=="size")
            {
                cout<<v.size()<<endl;
            }
