Queue is an abstract data structure, somewhat similar to Stacks. Unlike stacks, a queue is open at both its ends. One end is always used to insert data (enqueue) and the other is used to remove data (dequeue). Queue follows First-In-First-Out methodology, i.e., the data item stored first will be accessed first.
The power point presentation shows the Implementation of Queue operations using arrays and Linked List. Further, It also demonstrates about Circular queue operations.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

3. What is a
Stack?
A stack is a data structure of ordered items suc
h that items can be inserted and removed only
at one end.
• A stack is a LIFO (Last-In/ First-Out) data
structure
• A stack is sometimes also called a pushdown
store.
• What are some applications of stacks?
Program execution
Parsing
Evaluating postfix expressions
4. PUSH
Place an item on the Stack
PEEK
Look at the item on top of the stack, but do not
remove it.
POP
Look at the item on the stack and remove it.
What
can we
do with
Stack?
5. Stacks
Using a IStack
A balance of braces.
- (()) balanced braces
- ()(()()))) not balanced braces
How can you use Istack to check a br
ace is balanced or not?
Interface IStack Answer:
Problem
When you implement the above requirement, you ignore the implementation details of Istack.
What happens if we try to pop an item off the stack
when the stack is empty?
This is called a stack underflow. The
pop method needs some way of telling
us that this has happened. In java we
use the
java.util.EmptyStackException
Interface Istack
{
boolean empty();
void push(char c);
char pop();
char peek();
}
6. Implementing a
stack using an
array is fairly easy.
• The bottom of the stack is at
data[0]
• The top of the stack is at
data[numItems-1]
• push onto the stack at
data[numItems]
• pop off of the stack at
data[numItems-1]
Implementing a
stack using a
linked list isn’t
that bad either…
• Store the items in the stack in a linked
list
• The top of the stack is the head node,
the bottom of the stack is the end of
the list
• push by adding to the front of the list
• pop by removing from the front of the
list
7. Reversing A Word
We can use a stack to reverse the letters in a word. How?
Read each letter in th
e word and push it o
nto the
stack
When you reach
the end of the
word, pop the
letters off the stack an
d print them out.
8. What is a
Queue?
A data structure of ordered items such that item
s can be inserted only at one end and removed a
t the other end.
e.g. A line at the supermarket
• A queue is called a FIFO (First in-First out)
data structure.
• What are some applications of queues?
Round-robin scheduling in processors
Input/ Output processing
Queueing of packets for delivery in
networks
9. What we can do with Queue?
These ops are called insert ant getfront in order to simplify things.
Add an item to the queue.
Enqueue
Remove an item from the
queue
Dequeue
10. Implementation of
Queue
• Just like a stack, we can implementing a queue in two ways: 1) Using an array
2). Using a linked list.
Problems: Using an array to implement a queue is significantly harder than using
an array to implement a stack. Why?
Solution: Unlike a stack, where we add and remove at the same end, in a queue we
add to one end and remove from the other.
Implementing a queue using a
linked list is still easy:
• Front of the queue is stored as the head node
of the linked list, rear of the queue is stored
as the tail node.
• Enqueue by adding to the end of the list
• Dequeue by removing from the front of the
list.

Option 2 Sketch of Insert
Option 2 sketch of
getforce
Enqueue at data[0] and shift all of
the rest of the items in the array
down to make room.
Dequeue from data[numItems-1]
• Enqueue at data[rear+1]
• Dequeue at data[front]
• The rear variable always contains the
index of the last item in the queue.
• The front variable always contains the
index of the first item in the queue.
• When we reach the end of the array,
wrap around to the front again.
insert(Object item)
{
if(manyItems == 0) front = rear = 0;
else rear = (rear + 1) mod size;
data[rear] = item;
manyItems++;
}
Object getFront()
{
answer = data[front];
front = (front + 1) mod size;
manyItems--;
return answer
