WebFeb 4, 2024 · 1. LRU is like FIFO, except when something in the queue is referenced, it gets moved to the back of the queue. So you need to find a sequence where by moving one item (A) to the back of the queue, LRU chose to evict (B) whereas FIFO evicted (C), then (B) appeared in the sequence before (A), so LRU had to re-fetch (B) while FIFO didn't. – …
