HTTP Server

• Implements a robust HTTP server responding to GET requests on the /data endpoint.
• Supports query parameters:
  • n: File name
  • m: Line number
• Adheres to the following rules:
  • If both n and m are provided, it returns the content of the file /tmp/data/n.txt at line number m.
  • If only n is provided, it returns the entire content of the file /tmp/data/n.txt.

File Structure

• Efficiently handles files of approximately 100MB in size.
• More than 30 different files, ranging from 1.txt to n.txt.

Docker Image

• The server is bundled into a Docker image named Dockerfile.
• The Dockerfile is compatible with both ARM architecture and x86.
• Exposes port 8080.
• Configured to allocate a maximum of 1500 MB RAM and 2000m/2 Core CPU for the Docker container.
