The template is on the composers in ~saunders/320/tree234/. Write the function display in the Dict class in tree234.h. Test with "make run". This compiles rand from tree234.h and randMain.cc (using the 2,3,4 tree version of Dict instead of the red-black tree version) and runs it on a short test case (filename: illustration) in which the characters are keys. With your display function implemented, rand will display the characters in ascii order.
Note: this problem has a particularly easy solution. If you find yourself writing complex code, rethink the problem.
Because this template was just made available on Oct 9, you may submit this problem (only) up to Fri, Oct 13, by email. However, submission with the other problems on Wed is preferred.
