EC2 LAUNCHING

 

EC2

Step 1: Launch EC2 Instance

Go to: AWS Console --> EC2 --> Launch Instance

Configure:

  • Name: my-web-server
  • AMI: Amazon Linux 2 (easy for beginners)
  • Instance Type: t2.micro (free tier)

Step 2: Key Pair

  • Create or select a key pair.

Step 3: Network Settings 

Allow these:

  • SSH (port 22) --> for login
  •  HTTP (port 80) --> for web access

Step 4: Launch Instance

Click Launch Instance

Step 5: Connect to Instance

Use:

  • EC2 --> Connect --> EC2 Instance Connect (easiest)

OR via terminal:

with this command.

for this you have to download the pem files while selecting the key pair. 

ssh -i your-key.pem ec2-user@<public-ip>

Step 6: Install Web Server

For Amazon Linux:

sudo yum update -y
sudo yum install httpd -y

Step 7: Start Web Server

sudo systemctl start httpd
sudo systemctl enable httpd

Step 8: Add a Web Page

echo "Hello from EC2" | sudo tee /var/www/html/index.html

Step 9: Get Public IP

Go to EC2 dashboard --> copy:

Step 10: Access from Browser

THE DELIVERY MAN

  The Delivery Man – Python List Operations  Introduction Lists in Python are used to store multiple items in a single variable. They are flexible, allowing us to add, remove, update, and manipulate elements easily. In this task, different list operations are performed to simulate a delivery man's workflow. 1. Creating a list and accessing an item items = ["Notebook", "Pencil", "Eraser", "Ruler", "Marker"] print(items[2]) Approach: Indexing Why: Lists use zero-based indexing, so the third item is accessed using index 2. 2. Adding a new item items.append("Glue Stick") print(items) Approach: append() method Why: It adds an item at the end of the list, which is ideal for adding new deliveries. 3. Inserting an item items.insert(2, "Highlighter") print(items) Approach: insert() method Why: Used when we need to add an item at a specific position instead of the end. 4. Removing an item items.remove("Ruler...

SORT A LINKED LIST USING MERGE SORT

  Sort a Linked List using Merge Sort Introduction Sorting a linked list efficiently is a common problem in data structures. Unlike arrays, linked lists do not allow direct access to elements, so algorithms like quicksort are not ideal. Merge Sort is the best choice for linked lists because: It does not require random access It works efficiently with node-based structures Problem Statement Given the head of a linked list: Sort the list in ascending order Return the sorted linked list Example Input: 10 -> 30 -> 20 -> 40 -> 60 -> 50 Output: 10 -> 20 -> 30 -> 40 -> 50 -> 60 Solution Code class Solution: def mergeSort(self, head): if not head or not head.next: return head mid = self.getMiddle(head) next_to_mid = mid.next mid.next = None left = self.mergeSort(head) right = self.mergeSort(next_to_mid) return self.merge(left, right) def getMiddle(self,...
