Question: A simple scheme to translate a VPN to a PFN using an inverted page table would be to search the table sequentially from the beginning of the table until the VPN is found in an table entry, of which index is the PFN for the VPN. If there is no match, it is a page fault. This scheme looks very expensive because of the sequential search. Can you think of a better (reasonable) idea (i.e., a better mapping function) to maintain the inverted page table? Explain your idea. Just a few short sentences that explain the idea are enough
