Challenge Problems
Push your limits with advanced challenges
Given a sequence of page references (7, 0, 1, 2, 0, 3, 0, 4) and three memory frames, how many page faults occur under the Optimal Algorithm?
💡 Hint: Consider how you choose which pages to evict.
If a system uses LRU with the following reference string and memory frames (1, 2, 3, 1, 4, 1, 2, 5), calculate the number of page faults.
💡 Hint: Track the pages that remain in memory based on their usage.
