This practice problem will require you to implement a simple Queue class, supporting some common functions.

The expected header is as follows (p029.h):

#ifndef _P029
#define _P029
#include "mylist.h"
class Queue {
    private:
        MyList list;
    public:
        bool empty();
        int front();
        void push(int val);
        int pop();
};
#endif

Your task is to implement the actual functions for this class. You can use your own MyList implementation, or you can download the reference version here (https://jetic.org/download/mylist_linux.zip; https://jetic.org/download/mylist_macOS.zip):

mylist.h
mylist.o
