Answer 1

Code implemented in c++

used structure to store name,release_date,stars

implement as mentioned above

#include<bits/stdc++.h>
using namespace std;
struct movie{
   string name;
   string releasedate;
   vector<pair<string,string> > l;  
};
bool comp(movie a,movie b){
   return a.name<b.name;
}
bool sortbysec(const pair<string,string> &a, const pair<string,string> &b)
{
    return (a.second < b.second);
}
int main(){
   ifstream fin;
   string lin;
   string line;
   vector<string>data;
   vector<movie> movielist;
    fin.open("movielist.txt");
    movie m;
    while (fin){
        getline(fin, line);
        data.push_back(line);
    }
    fin.close();
    int f1=0,f2=0;
    for(int i=0;i<data.size();i++){
        if(data[i].length()==0){
           f1=0;f2=0;
           sort(m.l.begin(),m.l.end(),sortbysec);
           movielist.push_back(m);
           m.l.clear();
        }
        if(f1&&f2){
           vector<string>out;
           istringstream ss(data[i]);
           do {
               ss >> line;
               out.push_back(line);
           } while (ss);
           string second;
           for(int j=1;j<out.size()-1;j++){
               second+=out[j]+" ";
           }
           m.l.push_back(make_pair(out[0],second);
        }
        if(f1==1&&f2==0){
           m.releasedate=data[i];
           f2=1;
        }
        if(data[i].length()&&f1==0){
           m.name=data[i];
           f1=1;
        }
    }
   sort(movielist.begin(),movielist.end(),comp);
   for(int i=0;i<movielist.size();i++){
       cout<<movielist[i].name<<endl;
       cout<<movielist[i].releasedate<<endl;
       for(int j=0;j<movielist[i].l.size();j++){
           cout<<movielist[i].l[j].first<<" "<<movielist[i].l[j].second<<endl;
       }
       cout<<endl;
   }
}
