### Postfix Expression Evaluation Using Stack ADTAn application of the Stack ADT (Abstract Data Type) is the evaluation of postfix expressions. The following is a pseudocode algorithm for the postfix expression evaluation:1. **Scan the given postfix expression.**2. **For each symbol in the postfix expression:** - If the symbol is an operand, push its value onto a stack (Stack S). - If the symbol is an operator, perform the following steps: - Pop the top value from the stack; assign it to `operand2`. - Pop the next top value from the stack; assign it to `operand1`. - Apply the operator to `operand1` and `operand2` (i.e., compute `operand1 op operand2`). - Push the result back onto the stack.3. **Return the value that is on the top of the stack.**#### Pseudocode:```scan given postfix expression;for each symbol in postfix if operand then push its value onto a stack S; if operator then { pop operand2; pop operand1; apply operator to compute operand1 op operand2; push result back onto stack S; }return value at top of stack;```#### Example:Evaluate the following postfix expression: `6 5 3 + 2 12 * + 5 % +`To solve this expression using the stack algorithm:1. **Scan** `6` and push to the stack. Stack: `[6]`2. **Scan** `5` and push to the stack. Stack: `[6, 5]`3. **Scan** `3` and push to the stack. Stack: `[6, 5, 3]`4. **Scan** `+` (operator); pop `3` and `5`, compute `5 + 3 = 8`, then push the result `8` back to the stack. Stack: `[6, 8]`5. **Scan** `2` and push to the stack. Stack: `[6, 8, 2]`6. **Scan** `12` and push to the stack. Stack: `[6, 8, 2, 12]`7. **Scan** `*` (operator); pop `12` and `2`,

According to postfix expression pseudcode When there is operand then push value of operand into…

Recall that an application of the Stack ADT is postfix expression evaluation. As a reminder, here is pseudocode for the algorithm: scan given postfix expression; for each symbol in postfix if operand then push its value onto a stack S; if operator then ( pop operand2; pop operand1; apply operator to compute operand1 op operand2; push result back onto stack S; return value at top of stack; Evaluate the following postfix expression: 6 5 3 + 2 12 5 % +

You are allowed to operate on a stack WORK and a temporary stack TEMP (ifneeded) supporting their ADT operations of PUSH (S,X), POP (S, X) andEMPTYSTACK (S) only, where X represents an element/variable to be pushed in orpopped out of the stack and S represents a stack. You are also permitted to use onevariable if needed to carry out the operations.i) Given n distinct random numbers that are to be pushed into WORK, how canyou find the minimum element that was pushed into it? You are permitted to use alone variable.ii) Given n distinct random numbers that are to be pushed into WORK, how canyou find the maximum element that was pushed into it, all the while ensuring thatthe elements stored in WORK are in their descending order with the maximumelement beginning at the bottom of stack? You are permitted to use a lone variableand a temporary stack TEMP.iii) Given an array A[1: n] of distinct random numbers how can you obtain thesorted list in the array, making use of stacks alone?
The insert function first checks if the list is empty then head is updated, if the list is not empty then a new node is inserted at the tail. The delete function deletes the given node (temp). This temp node can be anywhere in the list. Your task is to update the insert and delete function code so that it implements the stack rule. i-e last in first out. The insert function should only allow insertion at head and the delete function should only pop the last inserted element (no parameter to be passed to the delete function). #include <iostream> using namespace std; class Node{ public: int data; Node *next; }; class List{ public: Node *head; List(){ head = NULL; } void insert(int data){ Node *nn = new Node; nn->next = NULL; nn->data = data; if(head==NULL){ head = nn; cout<<"Node inserted successfully at head"<<endl; } else{ Node *temp…
Project Overview: This project is for testing the use and understanding of stacks. In this assignment, you will be writing a program that reads in a stream of text and tests for mismatched delimiters. First, you will create a stack class that stores, in each node, a character (char), a line number (int) and a character count (int). This can either be based on a dynamic stack or a static stack from the book, modified according to these requirements. I suggest using a stack of structs that have the char, line number and character count as members, but you can do this separately if you wish.Second, your program should start reading in lines of text from the user. This reading in of lines of text (using getline) should only end when it receives the line “DONE”.While the text is being read, you will use this stack to test for matching “blocks”. That is, the text coming in will have the delimiters to bracket information into blocks, the braces {}, parentheses (), and brackets [ ]. A string…
A letter means enqueue and an asterisk means dequeue in the following sequence. Give the sequence of values returned by the dequeue operations when this sequence of operations is performed on an initially empty LIFO stack: S O * B E A U * * * T * I F * * U L *. What is front and back values? (Write your answer in uppercase letters separated by comma(,) only. No need to write "front" and "back".) *

You are given a mathematical expression in postfix notation (RPN). During the postfix expression evaluation algorithm, enter the value that would be at the bottom of the stack after processing the 6th token on the following input: 372-+ 6 * (Note this is not about expression trees, this is just the stack-based algorithm for evaluating a post fix expression.)
You are given N elements and your task is to Implement a Stack in which you can get a minimum element in O(1) time. Example 1: Input: push(2) push(3) pop() getMin() push(1) getMin() Output: 2 1 Explanation: In the first test case for query push(2) Insert 2 into the stack. The stack will be {2} push(3) Insert 3 into the stack. The stack will be {2 3} pop() Remove top element from stack Poped element will be 3 the stack will be {2} getMin() Return the minimum element min element will be 2 push(1) Insert 1 into the stack. The stack will be {2 1} getMin() Return the minimum element min element will be 1.
Given a stack, a function is consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] top The function should return false due to reverse order. Note: There are 2 solutions:first_is_conse cutive: it uses a single stack as auxiliary storagesecond_is_cons ecutive: it uses a single queue as auxiliary storage
Please, Add a display function that prints the stack using FIFO(first in first out) {printed in the sequence they were entered} Do not use for loop. this is stack implementation. not your normal for loop.
