A Deeper Look at HTTP Requests

In this article, we looked in how HTTP requests like GET, PUT and others are formed, how websites interact with them and the response send back.

Software Engineering

XMLHttpRequest to make HTTP requests

XMLHttpRequest can be defined as an API in the form of an object which is used to transfer data between the web browser and the web server. It gives us the ability to update parts of a web page without reloading the whole page

Hashing in C++ using std::hash

In this article, we will cover how hashing is natively supported in C++ through STL (std:hash) and how we can use it to generate hash of any object in C++.

Algorithms

Autocomplete feature using TRIE Data Structure

Autocomplete is a feature of suggesting possible extensions to a partially written text and is widely used in search engine, code IDEs and much more. Trie data structure is a perfect fit to implement this feature efficient in terms of memory and time [O(length of string)].
