Construct an expression tree from a given postfix notation and print the infix notation. There is a unique directed path from the root r to any node a. Thus, according to the final family tree a is the paternal uncle of f.
This is a tool to convert any infix expression to postfix expression with all steps shown in the table.
Using a stack to temporarily store operators is necessary because as we are evaluating each operator token of the infix expression from left to right, we can't instantly know an operator's.
