Hash table is a data structure designed for quick look ups and insertions. On average, its complexity is O(1) or constant time. The main component of a hash table is its hash function. The better the hash function, the more accurate and faster the hash table is. High level process of implementing a hash table is as follows: data is
Serverless technology is taking over the back-end development world. Some businesses are already dumping microservices infrastructure and switching to serverless. However, the learning curve for serverless is pretty steep and it comes with great complexity. Netlify is trying to solve that problem by providing create & drop functions. In this article, we learn about the main concepts of serverless technology
In the last installment, we learned about the basics of Umbraco and what is new in Umbraco 8. Now we are going to delve into coding basic functionality and making our code as modular as possible. Before we delve into the code, let’s talk a little about the different types of controllers available to us and which one is appropriate
Whether we know it or not, trees are everywhere: our computer file systems, HTML DOM, XML/Markup parsers, PDF format, computer chess games, compilers, and others heavily rely on the tree data structure. More practical examples are company hierarchies, family trees, or comments section of any posts. Trees are found to be tricky when implementing in applications and during the coding
Outline Binary search trees BST Implementation Binary Heaps Trie Binary Search Tree A binary search tree is a binary tree with a unique feature – all nodes to the left of the current node must be smaller than the current node and all nodes to the right must be larger. This rule must be valid for all of the nodes in the tree, not just for the root
Prerequisites: Basic knowledge of JavaScript You might be thinking, why would you even want to build a “Blockchain” system with JavaScript. Isn’t it a language to make websites? Well, it is. But it can also be used to explain the concepts of blockchain in a simple way. Blockchain is already way to big to ignore. Some people still think that blockchain is

In the last article, titled “Exploring React Native”, we used a few components to create a simple app. The app consisted of an Image component, a couple Text components, data that changed with user interaction, and a couple of buttons created with the Button component and TouchableOpacity component. We styled each component and at the end, had a counter app.
Previously, in “Exploring React Native (Continued Part 1), we continued to work on our simple app. The app initially consisted of an Image component, Text components, state with data, a couple of TouchableOpacity buttons and styling. The app was to keep track of the number of raccoons the user saw but we wanted to add to it. So, we add
