Least Recently Used (LRU)

Least Recently Used (LRU) is a method for managing data in memory, ensuring that the most relevant information is kept accessible. When space runs low, LRU identifies and removes the data that hasn't been used for the longest time. This approach assumes that if you haven't needed certain information recently, you're less likely to need it in the near future. LRU is commonly used in computer systems, like caches and virtual memory, to optimize performance by retaining frequently accessed data while efficiently managing limited storage resources.
