1. In Stacks topic, create GUI using python (tkinter) for Infix to Postfix Algorithm. Scope Animated/GUI Infix to postfix Algorithm using Python Project requirements i. Program should be able to accept infix expression from user and convert to postfix ii. Display all the infix expression one by one process to postfix expression. For example, 3 columns of Input, Stack and Output, with rows based on the length of input of infix i Option for evaluation of the postfix expression. For instance, from the input of infix expression AB+C D, user can evaluate A-10, B-5 and so on (any numbers) The following arithmetic operations are allowed in an expression + addition - subtraction multiplication / division A exponentiation % modulus [Note: We assume left to right associativity for all operators for the purpose of this Project.] The stack should be maintained with stack nodes, each containing a data member and a pointer to the next stack node Some of the functional capabilities Some of the functional capabilities you may want to provide are a) function convertToPostfix that converts the infix expression to postfix notation b) function isOperator that determines whether c is an operator c) function precedence that determines whether the precedence of operator1 is less than, equal to or greater than the precedence of operator2 (the function returns-1, 0 and 1, respectively) d) function push that pushes a value onto the stack e) function pop that pops a value off the stack f) function stackTop that returns the top value of the stack without popping the stack g) function isEmpty that determines if the stack is empty h) function printStack that prints the stack
