HTTP/1.1 is the older version with persistent connections, HTTP/2.0 introduces multiplexing and server push, and HTTP/3.0 uses QUIC protocol for faster performance.
HTTP/1.1 uses persistent connections for each request/response, leading to potential performance issues.
HTTP/2.0 introduces multiplexing, allowing multiple requests/responses to be sent over a single connection simultaneously.
HTTP/2.0 also supports server pu...
Print all possible subsets from a given slice of integers
Use recursion to generate all possible subsets
For each element in the slice, include or exclude it in the subset
Keep track of the current subset being generated
Context package in Go language provides a way to pass around deadlines, cancellation signals, and other request-scoped values.
Context package is used to manage deadlines, cancellation signals, and request-scoped values in Go programs.
It allows passing data between function calls without having to pass them explicitly as arguments.
Context package is commonly used in web servers to manage request-specific data and timeou...
REST API is a standard protocol for web services using HTTP, while gRPC is a high-performance, open-source RPC framework.
REST API uses HTTP for communication, making it easy to implement and widely supported.
gRPC is a modern, high-performance RPC framework that uses HTTP/2 for transport and Protocol Buffers for serialization.
gRPC is more efficient in terms of performance and supports features like bidirectional streami...
Use copy() function to create a new slice and reflect changes in original slice to the new slice.
Use the copy() function to create a new slice with the same length as the original slice.
Make changes to the original slice.
The changes made to the original slice will automatically reflect in the new slice as well.
GoLang is best for its simplicity, efficiency, concurrency support, and strong community backing.
Efficient performance due to compiled nature and garbage collection
Concurrency support with goroutines and channels
Strong standard library with built-in support for networking, encoding, and more
Simple and clean syntax that promotes readability and maintainability
Growing community and ecosystem with popular frameworks like
Kubernetes is an open-source container orchestration platform for automating deployment, scaling, and management of containerized applications.
Kubernetes follows a master-slave architecture with a master node controlling multiple worker nodes.
Master node components include API server, scheduler, controller manager, and etcd.
Worker node components include kubelet, kube-proxy, and container runtime (e.g. Docker).
Kubernet...

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed
A program to print all prime numbers
Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.

OOPs concepts are the fundamental principles of object-oriented programming.
Encapsulation - binding data and functions that manipulate the data
Inheritance - creating new classes from existing ones
Polymorphism - ability of objects to take on many forms
Abstraction - hiding implementation details and showing only functionality
Storage classes in C define the scope and lifetime of variables.
There are four storage classes in C: auto, register, static, and extern.
Auto variables are local to a block and have automatic storage duration.
Register variables are stored in CPU registers for faster access.
Static variables have a lifetime throughout the program and are initialized only once.
Extern variables are declared outside any function and can be a
