Initially C++ present in the tags… Test can be on cpp.sh

#include <iostream>
#include <vector>

int main()
{
    std::string algorithm_sorting ("1101001011");
    std::vector <std::string> video = {"a1","a2","a3","a4"};
    std::vector <std::string> picture = {"b1","b2","b3","b4"};
    std::vector <std::string> result;
    size_t v = 0, p = 0;
    for(auto&x:algorithm_sorting)
    {
        if(x=='1')
        {
            if(v < video.size()) result.push_back(video[v]);
            v++;
        }
        else
        {
            if( p < picture.size()) result.push_back(picture[p]);
            p++;
        }
    }
    for(auto&x:result)std::cout<<x<<" ";
