Preparing for interviews and I came across something that is making me question my understanding of big O constant time algorithms. A question on LeetCode asks to create a solution to the LFU cache

Dec 7, 2015 · What I could find was a which described using both MFU and LFU, most frequently used references are moved to primary cache for faster access and least frequently used references are …

Jul 10, 2012 · I'm trying to implement LFU (Least Frequently Used) cache using pure STL (I don't want to use Boost!). Requirements are: Associative access to any element using a Key like with std::map.

Nov 22, 2021 · I'd expect LFU to implement the 2nd strategy, because once you have entries with different ages in your cache, you have to account for them having less or more time to accumulate …
