Reversing a Linked List

Classes:

The LinkedList class
The Node class
The test program

Because the program takes from the input, we can make "test suites", files which define, in a sense, what exactly we mean when we say that our program works. Although we may have a sense that our program always works, on all inputs, strictly, it is only correct to say that it has worked on certain inputs. The test_i.txt files are those inputs that we know the program works. Hopefully, all inputs are shown to work by extrapolating from the behaviour of the small number of test files.

Test files:

Test 1: purposefully left blank. (Output)
Test 2: insert three lines at tail. (Output)
Test 3: insert three lines at head. (Output)
Test 4: insert five lines, at head and tail, intermixed. (Output)
