Given the following list initialization:

int fill[] = {12, 15, 7, 42, 43, 9, 11, 52, 30, 10};list ex2(fill, fill+sizeof(fill)/sizeof(int));

What is output by each of the following code segments?

a. cout << ex2.size() << " " << ex2.front() << " " << ex2.back();b. cout << *ex2.begin() << " " << * (--ex2.end()) << " "        << *ex2.rbegin() << " " << * (--ex2. rend()) ;c. ex2. insert (++ex2.begin() , 99);   ex2.pop_back() ;   cout << *ex2.begin();d. list:: iterator i = ex2.begin();   while (i != ex2.end())     if (*i%2 == 0)       i = ex2.erase(i);     else       i++;for (i = ex2.begin(); i != ex2.end(); i++)  cout << *i << endl;e. list::iterator i;   ex2. sort () ;   for (i = ++(++ex2.begin()) ; i != ex2.end(); i++)     cout << *i << endl;
