Recall that one application of a Stack is to process an arithmetic expression written in postfix notation. We can
also represent arithmetic expressions as a tree. Your job is to write a function that will convert a Stack of singleton
expression nodes (where all the left and right pointers are initially set to NULL) into the correct tree structure. Note that
you do not need to actually calculate the âanswerâ to the arithmetic expression. Here is an example:
