Formulate a formal definition of a 2-stack Pushdown automaton. The intuitive idea is that you should augment the definition of an ordinary 1- stack Pushdown automaton, except now you have two stacks. (You should state what it is, what a sequence of operations constitutes a valid sequence of moves on an input, and what constitutes acceptance.)

Please Help with this questions with short explanation thank you

Consider the pushdown automaton with the following transition rules: 1.8(0,0,20) = {(q,XZ0)} 2. 8(9,0,X) = {(q,XX)} 3. 8(q,1,X) = {(q,x)} 4. 8(q,£,X) = {(p,ɛ)} 5. 8(p,£,X) = {(p,ɛ)} 6.8(p,1,X) = {(p,XX)} 7. 8(p,1,20) = {(p,ɛ)} From the ID (p,1101,XXZ0), which of the following ID's can NOT be reached? (p,101,XZO) (p,101,XXXZO) (2,01,XXXXXZO) O (p,01,8) Here are the transitions of a deterministic pushdown automaton. The start state is qo, and f...

Objective To acquire expertise in stack manipulation and management, subroutine linkage and return conventions, and recursive procedures. Description You are to create a MIPS programming assignment that returns postfix representation of the input and create an expression tree. Your MIPS program should make use of the expression tree to store the input and provide, by means of an adequate traversal, the value for the expression. Your solution should be structured according to the following steps: Step 1: Convert expression from...
You will write the following files: mystack.h - contains the class definition for the mystack class. mystack.cpp - contains the definitions for member functions of the mystack class. inpost.cpp - contains your convert() function. inpost.h - contains the function prototype for convert() so that the main() can call it. Each of the files (with the exception of inpost.h) is described in more detail below. All header files should contain header guards to prevent them from being included multiple times in...
I'm having trouble writing this code, can some help me? Step 1: Capturing the input The first step is to write a functionGetInput()that inputs the expression from the keyboard and returns the tokens---the operands and operators---in a queue. You must write this function. To make the input easier to process, the operands and operators will be separated by one or more spaces, and the expression will be followed by #. For example, here’s a valid input to your program: 6...
JAVA, please You must write a robust program meaning that your program should not crash with any given data. Data validation must be done any time that user enters an input. Write a program that 1. Gets an infix expression form the user and evaluate the expression using stack ADT a. Finds the postfix equivalent of the given infix expression b. Evaluate the created postfix expression. c. Note: your program should not crash when you enter an invalid expression such...
Lab 3 – Array-Based Stack and Queue Overview In this assignment, you will be implementing your own Array-Based Stack (ABS) and Array-Based Queue (ABQ). A stack is a linear data structure which follows the Last-In, First-Out (LIFO) property. LIFO means that the data most recently added is the first data to be removed. (Imagine a stack of books, or a stack of papers on a desk—the first one to be removed is the last one placed on top.) A queue...

Question Remember: You will need to read this assignment many times to understand all the details of the you need to write. program Goal: The purp0se of this assignment is to write a Java program that models an elevator, where the elevator itself is a stack of people on the elevator and people wait in queues on each floor to get on the elevator. Scenario: A hospital in a block of old buildings has a nearly-antique...

1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...
