#include<iostream>
#include<vector>using namespace std;int len,n,nb,op,maxx,minn;
int arr[100];

}                                 

vector的两种遍历：

vector<int>vec;for(int i=0;i<vec.size();i++){vec[i];}

vector<int>vec;vector<int>::iterator iter;for(iter=vec.begin();iter!=vec.end();iter++){*iter;
}

vector 删除

  vec.erase(iter);
vec.erase(vec.begin(),vec.end());
