For all of the following problems, when it is stated “in the user level” you should assume that you only have the object code of the data structure along with the interface given in the header file. On the other hand, When it is stated that “in the implementation level” you should assume that you have the source code file of the data structure and you should write the desired piece of code within that source code file.
