stack = []
# Push
stack.append(10)
stack.append(20)
# Pop
print(stack.pop()) # 20
# Peek
print(stack[-1]) # 10
# Check empty
print(len(stack) == 0)
2️⃣ What is a Queue?
A Queue is a First-In-First-Out (FIFO) structure.
Think of a line at a ticket counter: first come, first served.
Operations:
• enqueue(item) – Add item to the rear
• dequeue() – Remove item from the front
• peek() – View front item
• is_empty() – Check if queue is empty
Python Implementation (Using collections.deque)
from collections import deque
queue = deque()
# Enqueue
queue.append(10)
queue.append(20)
# Dequeue
print(queue.popleft()) # 10
# Peek
print(queue[0]) # 20
# Check empty
print(len(queue) == 0)
3️⃣ Stack Using Linked List (Python)
class Node:
def __init__(self, data):
self.data = data
self.next = None
class Stack:
def __init__(self):
self.top = None
def push(self, data):
node = Node(data)
node.next = self.top
self.top = node
def pop(self):
if not self.top:
return None
data = self.top.data
self.top = self.top.next
return data
4️⃣ Queue Using Linked List (Python)
class Node:
def __init__(self, data):
self.data = data
self.next = None
class Queue:
def __init__(self):
self.front = self.rear = None
def enqueue(self, data):
node = Node(data)
if not self.rear:
self.front = self.rear = node
else:
self.rear.next = node
self.rear = node
def dequeue(self):
if not self.front:
return None
data = self.front.data
self.front = self.front.next
if not self.front:
self.rear = None
return data
📝 Practice Tasks
1. Implement a stack using a list
2. Implement a queue using a list
3. Reverse a string using a stack
4. Check for balanced parentheses using a stack
5. Simulate a queue using two stacks
Double Tap ♥️ For Morefunction reverseString(str) {
return str.split('').reverse().join('');
}
4️⃣ Find the max number in an arrayconst max = Math.max(...arr);
5️⃣ Write a function to check if a number is primefunction isPrime(n) {
if (n < 2) return false;
for (let i = 2; i <= Math.sqrt(n); i++) {
if (n % i === 0) return false;
}
return true;
}
6️⃣ What is closure in JavaScript?
Answer:
A function that remembers variables from its outer scope even after the outer function has returned.
7️⃣ What is event delegation?
Answer:
Attaching a single event listener to a parent element to manage events on its children using event.target.
8️⃣ Difference between == and ===
Answer:
- == checks value (with type coercion)
- === checks value + type (strict comparison)
9️⃣ What is the Virtual DOM?
Answer:
A lightweight copy of the real DOM used in React. React updates the virtual DOM first and then applies only the changes to the real DOM for efficiency.
🔟 Write code to remove duplicates from an arrayconst uniqueArr = [...new Set(arr)];
