Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have pages X, Y, Z in memory. Implement an Optimal Replacement Strategy for requests in the order: X, Y, W, Z, V, Y and specify which page gets replaced each time.

💡 Hint: Look ahead at the request sequence.

Challenge 2 Hard

Reflect on a scenario where the Optimal Replacement might result in worse performance compared to a simpler algorithm. What could cause this?

💡 Hint: Think about patterns in data requests.
