Calculating IP Address Ranges in Go: Learn IPv4 Range Between Addresses

Programming Problems & Solutions : “Exploring IP Address Ranges in Go”. The introduction to this series is here and includes all links to every post in the series. This is the 8th of a dozen programming challenges I’m doing to setup for an eventual blog post on AI coding. The intent is to setup these programming challenges, get a solution, find a good refactoring, and then see how the AI tooling performs going through the same thing or refactoring what is in place. If you’re interested in how AI performs, and checking out these experiments and tests, subscribe to the blog to have the articles delivered directly to your email!

Hey there, fellow code adventurers! Today, we’re diving into the world of IP addresses and ranges. We’ve got an exciting coding challenge on our hands, and we’ll be tackling it using the Go programming language. So, grab your favorite beverage, and let’s get started!

The Challenge

Our mission, should we choose to accept it, is to implement a function that takes two IPv4 addresses as input and returns the number of addresses between them (including the first one, but excluding the last one). We’ll be working with valid IPv4 addresses in the form of strings, and the last address will always be greater than the first one.

Converting 2D Arrays to CSV in Go: Problem-Solving and Testing

Programming Problems & Solutions : “Transforming 2D Arrays to CSV Format in Go”. The introduction to this series is here and includes all links to every post in the series. This is the 7th of a dozen programming challenges I’m doing to setup for an eventual blog post on AI coding.

Hey there, coding enthusiasts! Today, I’m diving into an interesting problem that involves converting a two-dimensional numeric array into its CSV (Comma-Separated Values) representation. This is a common task when working with data in various formats, and I’ll explore how to tackle it using Go.

The Problem: Imagine you have a 2D array filled with numbers, and you need to convert it into a CSV string. Each row of the array should be represented as a line in the CSV, with the elements separated by commas. For example, consider the following input array:

If you’d like to watch the video (see just below this), or the AI code up (it’s at the bottom of the post) they’re available! But if you just want to work through the problem keep reading, I cover most of what is in the video plus a slightly different path down below.

Hey there, fellow code wranglers! Time to dive deep into the land of bits and bytes and IP addresses. Today, I’m tackling a neat little programming challenge: converting an IPv4 address into a 32-bit integer. A fun exercise that hones your bitwise operation skills and deepens your understanding of IP addresses.

In software development, seemingly simple tasks can unfold into complex challenges, especially when it involves outputs that must be human-centric, such as formatting time durations into a readable format. This is the case with the task of converting seconds into an easily digestible format for users.

The Challenge

The objective is straightforward: write a function that converts a given number of seconds into a format easy for humans to read. If it’s zero seconds, the function should return “now”. Otherwise, it should represent the duration as a combination of years, days, hours, minutes, and seconds, following specific formatting rules.
