The document discusses stacks, which are linear data structures that follow the LIFO (last-in, first-out) principle. New elements are added to one end of the stack and only removed from that end. Main operations on a stack are push, which adds an element to the top, and pop, which removes the top element. The document also covers implementing stacks through methods like push(), pop(), top(), and display(), and provides examples of how each method works.

Stack
A stack is a Last In, First Out (LIFO) data structure where items added last are removed first. When an item is added to a stack, it is placed on the "top" of the stack, and when an item is removed it is taken from the top. Items are removed from the stack in the reverse order that they were inserted. The two main operations on a stack are PUSH, which adds an item to the top, and POP, which removes and returns the top item.
Data Structure (Stack)
Stack is a data structure that only allows elements to be added and removed from one end, called the top. It has components like a top pointer variable, elements that hold data, and a maximum size. Stacks can be implemented as arrays or linked lists. The main operations on a stack are push, which adds an element to the top, and pop, which removes an element from the top. These operations work similarly in array and linked list implementations, by incrementing or decrementing the top pointer and adding or removing the top element.
data structure, stack, stack data structure
The document discusses stacks, which are linear data structures that follow the LIFO (last in, first out) principle. Values are inserted into and retrieved from one end, called the top of the stack. The two main operations are push, which inserts a value into the stack, and pop, which retrieves a value. An example C program demonstrates these operations on a stack implemented with an array. The stack starts empty and grows as values are pushed on until it reaches its maximum size, at which point it is full. Values can be continuously popped off until the stack is empty again.
Stack operation
The document discusses stacks and their operations. A stack is a data structure that uses LIFO (Last In First Out) methodology to store and retrieve objects. Items are added to the top of the stack using a push operation and removed from the top using a pop operation. The top of the stack is dynamically determined as items are pushed on and popped off. Stacks can be implemented using static arrays that allocate fixed block of memory.
Stack Data Structure
The document discusses stack data structures. It defines a stack as a linear data structure that follows the LIFO (last in, first out) principle. Elements can only be inserted or removed from one end, called the top. Common stack operations include push to add an element, pop to remove an element, and functions to check if the stack is empty or full. Stacks have many real-world applications like processing function calls and arithmetic expressions.
Stack a Data Structure
The document discusses stacks, which are a fundamental data structure used in programs. It defines a stack as a linear list of items where additions and deletions are restricted to one end, called the top. Common stack operations include push, which adds an element to the top, and pop, which removes an element from the top. Stacks have applications in parsing expressions, reversing strings, implementing depth-first search algorithms, and calculating arithmetic expressions in prefix and postfix notation. Stacks can be implemented using static arrays or dynamic arrays/linked lists.
Project of data structure
The document discusses various applications of stacks including:
1) Reversing strings by pushing characters onto a stack and popping them off in reverse order.
2) Calculator operations using postfix notation and a stack.
3) Recursive functions using a stack to store previous function calls and variables.
4) Determining if a word is a palindrome by pushing characters onto a stack and comparing to the popped off characters.
Code examples are provided for reversing strings, recursive summation, and determining palindromes using stacks.
Queue
A queue is a first-in first-out (FIFO) data structure where elements are inserted at the rear end and deleted from the front end. It maintains two pointers - a front pointer pointing to the front element and a rear pointer pointing to the rear element. New elements are added by incrementing the rear pointer and elements are removed by incrementing the front pointer. Common queue operations include enqueue() to add an element, dequeue() to remove an element, peek() to access the front element without removing it, and functions to check if the queue is full or empty.

STACK ( LIFO STRUCTURE) - Data Structure
Stack which is known as LIFO structure.Which is type of the Linear data structure and it is Non-Primitive data structure.
Definition:Non primitive data structure are not a basic data structure and depends on other primitive data structure (Integer,float etc).
Non primitive data structure can't be operated by machine level instruction directly.
Difference between stack and queue
Stack and queue are non-primitive data structures that differ in their accessing and adding methods. A stack uses LIFO (last in first out), accessing the last added element first, while a queue uses FIFO (first in first out), accessing the first added element first. A key difference is that a stack has one open end for pushing and popping, while a queue has two open ends for enqueuing and dequeuing. Both data structures are based on real-world equivalents like stacks of CDs and queues for movie tickets.
basics of queues
The document describes how queues work and two methods for implementing queues - using an array or linked list. It explains that queues follow a first-in first-out (FIFO) ordering, with new elements added to the rear and elements removed from the front. The key queue operations of enqueue (add to rear) and dequeue (remove from front) are also defined. Implementation using an array requires tracking the number of elements, front index, and rear index, while a linked list uses head and tail pointers.

Queue
A queue is a first-in, first-out (FIFO) data structure with two ends - a front end for deletion and a rear end for insertion. Elements are inserted at the rear of the queue and deleted from the front. A queue can be implemented using either an array or linked list. Basic queue operations include enqueue, which inserts at the rear, and dequeue, which removes from the front. A circular queue addresses overflow issues by making the queue circular so the rear can loop back to the front when full.

Stacks are data structures that follow LIFO (last in, first out) ordering. Elements can only be added to or removed from one end, called the top. Stacks are used to maintain information between main programs and subroutines. Elements are pushed onto the stack by decrementing the stack pointer and storing the element, and popped off by incrementing the stack pointer after retrieving the element. Operations must check that the stack is not empty before popping or full before pushing to prevent errors.

Why does the stack use a FILO (first in last out) schemeSolutio.pdf
Why does the stack use a FILO (first in last out) scheme?
Solution
When a program starts executing, a certain contiguous section of memory is set aside for the
program called the stack.
A stack is a limited access data structure - elements can be added and removed from the stack
only at the top. push adds an item to the top of the stack, pop removes the item from the top. A
helpful analogy is to think of a stack of books; you can remove only the top book, also you can
add a new book on the top.
Hence when the elements are pushed onto the stack using push operations, the first element
pushes will be at the bottom of stack and the last element pushed in will be at top of stack.
Therefore when pop operation is executed , top element ( last element pushed in )of stack is
popped out first and hence first element pushed in popped out last.
Thereby Stack operates in LIFO (last in first out ) or FILO ( First In Last Out) Scheme.
Operation on stack
The document discusses stacks, which are linear data structures that follow the LIFO (last in first out) principle. Elements are inserted and deleted from one end called the top. The two main operations on a stack are push, which inserts an element, and pop, which deletes the top element. When pushing a new element, the stack must check for overflow if the top is already at maximum capacity. When popping an element, underflow occurs if trying to pop from an empty stack.
In C++ a function used to put data into a stack is typically called a.docx
In C++ a function used to put data into a stack is typically called a what?
Solution
Push function used to put data into a stack
A Stack is a data structure which works on the principle LIFO(Last In, First Out).The basic operations in a Stack are :
1. Push : In which we push the data into the stack.
2. Pop : In which we remove an element from the Stack.
All insertions and removals are done only from one side of the Stack , which is called the \'top\' of the Stack.
A stack is generally used in function calls where the local variables are pushed onto the Stack and when the function returns ,
it pops the variables from the Stack.
// Push operation to insert an element on top of stack.

The document discusses stacks, which are linear data structures that only allow insertion and removal of elements from one end. Stacks follow the LIFO (last in, first out) principle. The basic stack operations are push, which adds an element to the top, and pop, which removes the top element. Stacks can overflow if full and underflow if empty. Stacks can be implemented using arrays, with a pointer tracking the top index. Pseudocode provides algorithms for push and pop operations on a stack implemented using an array.
Introduction to stack
This document introduces stacks and their implementation using arrays. It defines a stack as a data structure that follows the LIFO (last in, first out) principle, where the last element added is the first removed. It describes how stacks can be modeled as a plate or coin stacker, with elements pushed onto the top and popped off the top. The key stack operations of push and pop are introduced, with push adding an element to the top and pop removing the top element. The implementation of stacks using arrays is then covered, with an array representing the stack and a variable tracking the top index. Pseudocode is provided for push and pop operations on the array-based stack.
Stack operation algorithms with example
This document discusses stacks and algorithms for common stack operations. It defines a stack as a last-in, first-out data structure where the last item added is the first removed. The key operations are PUSH to insert an item and POP to remove an item from the top. Algorithms are provided for PUSH, POP, and displaying the stack. As an example, the document shows the steps to convert an infix notation expression to postfix.
Stack PPT.pptx
Stack is a linear data structure that follows LIFO (Last In First Out) principle. Elements can only be inserted or removed from one end called the top. The two main operations on a stack are push and pop. Push inserts an element at the top, while pop removes an element from the top. A stack is generally implemented using an array, with push and pop functions to add or remove elements from the top. Push checks for overflow before incrementing the top pointer and inserting the element. Pop decrements top after removing the top element and returning it.
Lecture#5 - Stack ADT.pptx
A stack is a linear data structure that follows the LIFO (last-in, first-out) principle for adding and removing items. It allows push and pop operations at one end called the top. Common stack operations include push to add an item to the top, pop to remove the top item, peek to view the top item without removing it, and functions to check if the stack is empty or full. Stacks have applications in expression evaluation, backtracking, recursion, undo/redo operations, and graph searches like depth-first search. Recursive functions work by calling themselves during execution and are useful for implementing stacks.

This document discusses stacks, which are non-linear data structures that follow the LIFO (last in, first out) principle. Stacks have operations like push and pop that insert and remove elements from the top of the stack. Pushing adds an element and increments the top pointer, while popping removes an element and decrements the top pointer. Stacks have applications in expression evaluation, memory management, and recursion. The document provides algorithms and code examples for implementing push and pop operations on a stack.

A stack is a linear data structure that follows the LIFO (last in, first out) principle. Elements are inserted and removed from only one end, called the top. Common stack operations include push to insert an element, pop to remove an element, and peep to view elements. The program implements these operations using an array and tracks the top index, inserting and removing elements at that position.

This document discusses stacks and their use as a data structure. It begins by defining what a stack is, namely a data structure that follows the last-in, first-out (LIFO) principle. Common stack operations like push, pop, and peek are introduced. Examples are given of how stacks are used in applications like undo mechanisms, expression evaluation, and validating parentheses in expressions. The key operations and algorithms for implementing a stack are described, including pseudocode for push, pop, and display functions. Finally, examples are provided of how stacks can be used to reverse strings, validate parentheses, and convert infix expressions to postfix form.
Explain what does the following function do void foo (Stack s) { .pdf
Explain what does the following function do void foo (Stack *s) { while(!s rightarrow
isEmpty()) { cout
Solution
This function is written to call a stack which is a recursive data structure. A stack is basically a
collection of objects which is based on LIFO(Last In First Out) where the element that is inserted
at the last will be deleted first from the stack. To insert an element we use PUSH in a stack and
to delete we use POP.
TOP represents the top element in the stack.
In this program, function foo calls a stack s and in the while loop there is a condition (!s-
>isEmpty()) which checks whether the stack is empty or not. If the stack is not empty then the
program prints the top element of the stack (cout<top()) and then s->pop(); means that after
printing the top element pop opertaion is being called which deletes the top most element of the
stack.
So this program will delete all the elements of the stack until the stack is empty.
Example- the stack has elements inserted as 10,9,8,7. So the program will print 10,9,8,7 and will
delete them one by one. First 10 will be deleted then 9 and so on as stack follows a LIFO
structure..
Stack and its operations
This document discusses stacks and their operations. It defines a stack as a linear data structure that follows LIFO (last-in, first-out) ordering. Elements are inserted and removed from one end only, called pushing and popping. Stacks have common real-world examples like decks of cards. They can be represented using arrays or linked lists. The core stack operations are push, which adds an element, and pop, which removes the top element. Additional operations check the stack status, like if it is full or empty. Pseudocode is provided for implementing push, pop, and status checks in both array-based and linked list-based stacks.

1. Stacks are linear data structures that follow the LIFO (last in, first out) principle, where elements can only be inserted or removed from one end called the top. Common stack operations are push to add and pop to remove elements.
2. Stacks have two main implementations - using arrays or linked lists. Array implementations are faster but have size limits, while linked lists are dynamic. Push and pop operations on both are described.
3. Stacks have many applications including evaluating arithmetic expressions using postfix notation, which avoids the need for parentheses. The document describes converting expressions to postfix and an algorithm to evaluate them
DATA STRUCTURE - STACK
Stacks are data structures that follow the last-in, first-out (LIFO) principle. Elements are inserted and removed from the top of the stack. Common operations include push, which adds an element to the top, and pop, which removes the top element. Stacks have applications in expression evaluation, recursion, and parsing. They can be implemented using arrays or linked lists.

This document discusses stacks and their implementation in Python. It begins with an introduction to stacks and their LIFO (last-in, first-out) principle. Key operations on a stack like PUSH and POP are explained. The document then presents an implementation of a stack in Python using a list and defines functions for common stack operations. It also discusses applications of stacks, conversion between infix and postfix notation using a stack, and evaluating postfix expressions.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
