Hashmap is a data structure that stores key-value pairs and uses hashing to map keys to values for efficient retrieval.
Hashmap uses an array of linked lists to store key-value pairs.
When a key is inserted, its hash code is calculated to determine the index in the array where it will be stored.
If multiple keys have the same hash code (collision), they are stored in the same linked list at that index.
To retrieve a value,...
String is a data type used to represent text in programming. SCP stands for String Constant Pool, a memory area in Java for storing unique string literals.
String is a sequence of characters enclosed in double quotes.
SCP is a special memory area in Java where unique string literals are stored to save memory.
String literals are stored in SCP and reused if they already exist.

Implement LRU cache
LRU stands for Least Recently Used
It is a cache eviction policy that removes the least recently used item
It can be implemented using a doubly linked list and a hash map
Newly accessed items are moved to the front of the list
When the cache is full, the item at the end of the list is removed
Virtual memory is a memory management technique that allows a computer to use more memory than it physically has.
Virtual memory uses a combination of RAM and hard disk space to store data.
It allows programs to use more memory than is physically available.
If a program tries to access memory that is not currently in RAM, it will be swapped in from the hard disk.
Even if we had infinite RAM, virtual memory would still be n...

Implement a doubly linked list to keep track of the order of keys based on their usage.
Use a hashmap to store key-value pairs for quick access and updates.
When a key is accessed or updated, move it to the front of the linked list to mark it as the most recently used.
When the cache reaches...
Given an array of non-negative integers and an integer K representing the length of a subarray, your task is to determine the maximum elements for each subarray of size ...
Find the maximum elements for each subarray of size K in a given array.
Iterate through the array and maintain a deque to store the indices of elements in decreasing order.
Pop elements from the deque that are out of the current window.
Keep track of the maximum element in each subarray of size K.
Return the maximum elements for each subarray.
Virtual memory is a memory management technique that allows a computer to compensate for physical memory shortages by temporarily transferring data from RAM to disk storage.
Virtual memory allows programs to use more memory than is physically available on the system.
It helps in multitasking by allowing multiple programs to run simultaneously without running out of memory.
Virtual memory uses a combination of RAM and disk...
