![]() ![]() Any help would be appreciated and I'll leave all of my code for you guys below, thank you. The maximum number of symbols that will appear on. I am aware of how postfix notation, stacks and precedence works so the syntax approach I took seems to make sense to me however it seems to print it out in some sort of prefix notation with some duplicates at times, its really odd. Suppose that we are using the usual stack algorithm to convert the expression from infix to postfix notation. Push ( onto a stack and append ) to the tokenized infix expression list / queue. i.e Store each element i.e ( operator / operand / parentheses ) of an infix expression into a list / queue. You are already moving your scanner past the line read. ![]() Jump to Post Answered by verruckt24 438 in a post from 14 Years Ago scan.nextLine() String str scan.nextLine() This is what causes the problem. ![]() represent the LIFO principle by using push and pop. First, ensure that the string is received from the scanner. The given code accepts the expression from the user and display its postfix. I am trying to learn and implement some practical uses of stacks and I am doing a little program that takes in an equation and converts it to postfix notation. Algorithm to convert an Infix expression to a Postfix expression. In programming terms, putting an item on top of the stack is called push and removing an item is called pop. In this tutorial, you will learn how to convert expression from infix to postfix. ![]()
