Fall 2021 CpE 207 Data Structures java language Q5 [5 pts] Write an algorithm that converts a Prefix expression into a Postfix expression using a stack Read the Postfix expression from left to right If the symbol is an operand, then push it onto the Stack If the symbol is an operator, then pop two operands from the Stack Create a string by concatenating the two operands and the operator before them. string = operator + operand2 + operandi And push the resultant string back to Stack Repeat the above steps until end of Prefix expression. Important Note: 1. Your programs should be well-structures and well-documented. 2. Indicate the expected time complexity of Q3 and 24 2
