删除vector中的偶数元素，删除list中的奇数元素

#include<vector>
#include<list>
#include<iostream>
using namespace std;
int main()
{
    vector<int> vec={0,1,1,2,3,5,8,21,55,89};
    list<int> li={0,1,1,2,3,5,8,21,55,89};
    auto ve=vec.begin();
    auto it=li.begin();
    while(ve!=vec.end())
    {
        if(*ve%2)
            ++ve;
        else
            ve=vec.erase(ve);
    }
    while(it!=li.end())
    {
        if(*it%2)
            it=li.erase(it);
        else
            ++it;
    }
    for(auto v:vec)
        cout<<v<<" ";
    cout<<endl;
    for(auto i:li)
        cout<<i<<" ";
    cout<<endl;
    return 0;
}
