A hashmap is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hashmap uses a hash function to determine the index of the key-value pair in the underlying array.
Collisions can occur when two keys hash to the same index, which is resolved using techniques like chaining or open addressing.
Hashmap typically has an underlying array where each element is a linked...
LRU cache is a data structure that stores the most recently used items and removes the least recently used items when full.
Use a doubly linked list to keep track of the order of items based on their usage.
Use a hashmap to quickly access items in the cache.
When an item is accessed, move it to the front of the linked list to mark it as the most recently used.
SOLID principles are a set of five design principles in object-oriented programming to make software designs more understandable, flexible, and maintainable.
Single Responsibility Principle (SRP) - A class should have only one reason to change.
Open/Closed Principle (OCP) - Software entities should be open for extension but closed for modification.
Liskov Substitution Principle (LSP) - Objects of a superclass should be re...
I have worked with design patterns such as Singleton, Factory, Observer, and Strategy.
Singleton pattern ensures a class has only one instance and provides a global point of access to it.
Factory pattern creates objects without specifying the exact class of object that will be created.
Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified a...
Microservice design pattern focuses on breaking down a large application into smaller, independent services.
Each microservice is responsible for a specific function or feature
Communication between microservices is typically done through APIs
Microservices can be developed, deployed, and scaled independently
Examples: Netflix, Amazon, Uber

Memory management in Python involves automatic memory allocation and deallocation through garbage collection.
Python uses automatic memory management through garbage collection to allocate and deallocate memory.
Memory is managed using reference counting and a cycle-detecting garbage collector.
Python's memory management is efficient for most use cases, but can lead to memory leaks if circular references are not handled p
Garbage collection in Python is an automatic memory management process that helps in reclaiming memory occupied by objects that are no longer in use.
Python uses a built-in garbage collector to manage memory automatically.
The garbage collector in Python uses reference counting and a cycle-detecting algorithm to reclaim memory.
Explicitly calling the 'gc.collect()' function can trigger garbage collection in Python.
Garbage...
