Question: The LFU replacement on the upper part on string sequence 1123451 should be 5 page faults. The LFU on the bottom part on string sequence

The LFU replacement on the upper part on string sequence 1123451 should be 5 page faults. The LFU on the bottom part on string sequence 123452 should have 6 page faults. This is according to the feedback I got from someone on here. Please help me fix it.

4. Discuss situations in which the least frequently used (LFU) page replacement algorithm generates fewer page faults than the least recently used (LRU) page-replacement algorithm. Also discuss under what circumstances the opposite holds. Answer: Consider the following sequence of memory accesses ina system that can hold four pages in memory: 1123451.When page S is accessed, the least frequently used page-replacement algorithm would replace a page other than 1, and therefore would not incur a page fault when page 1 is accessed again. On the other hand, for the sequence 12 3452" the least recently used algorithm performs bette Strin reference: 112 345 LRu Repacement LFu Replaceanent 11'23u5 2 2 2 5 5 5 Poge fults Page fault = 7 Frequencies Strim reference 123452 LRU LFU LRu LFu Replacement I 234 52 221 2 2 FFFFF =5F Roge tultk 5 encies
