CMSC212 - Project #3
simplifyNode should return 0 when
change to the tree is
subtraction should be left-right (not right-left as could be infered from the project description).
The semantics of passing a NULL sub-tree to the create operations is un-defined. This means you should *not* write a test case to check that there is an expected behavior for creating an operatorNode when it is passed a NULL child.Your implementation of ast.c is free to either allow or reject this case as you wish.
