Sprint Challenge

Challenge Overview

This sprint challenge will test your understanding of the key concepts covered in this sprint, including:

• Stacks and queues implementation and operations
• Computer hardware components and OS interactions
• Immutability, final keyword, and their applications
• In-memory caching strategies and implementations

The challenge will consist of coding tasks and theoretical questions that will assess your knowledge of these topics. Make sure to review all modules before beginning the challenge.

Challenge Topics in Detail

// Example challenge task:
// Implement a method that determines if a string of brackets is balanced
public boolean isBalanced(String brackets) {
    Stack<Character> stack = new Stack<>();
    // Your implementation here
}

// Example challenge task:
// Identify issues with this immutable class implementation
public final class Person {
    private final String name;
    private final List<String> addresses;
    
    // Constructor and methods
    // Your analysis here
}

// Example challenge task:
// Implement a method that enhances this function with caching
public DataObject fetchExpensiveData(String key) {
    // Expensive operation that could benefit from caching
    // Your implementation here
}

Preparation Tips

• Review All Module Content: Ensure you've watched all videos and completed all module exercises
• Practice Implementation: Try implementing stacks, queues, and caches from scratch
• Study Code-Along Solutions: Understand the patterns and techniques demonstrated
• Review Learning Objectives: Focus on the specific learning objectives from each module
• Time Management: Plan to allocate enough time for each section of the challenge
