  • Question 1
    • What happens when you attempt to compile and run the following code?
       #include <iostream>
       #include <set>
       #include <list>
       using namespace std;
       int main(){
       int t[] ={ 1, 1, 2, 2, 3, 3, 4, 4, 5, 5 };
       list<int>v(t, t+10);
       multiset<int> s1(v.begin(),v.end());
       if (s1.count(3) == 2) {
       s1.erase(3);
       }
       for(multiset<int>::iterator i=s1.begin();i!= s1.end(); i++) {
       cout<<*i<<" ";
       }
