This article discusses solving a programming problem related to calculating the number of IP addresses between two IPv4 addresses. The solution, implemented in Go, involves parsing the IP addresses, converting them to integer representations, and handling various edge cases. The article also includes code refactoring for improved readability and compactness. Continue reading →

In this programming article, the author discusses converting a two-dimensional numeric array into a CSV string using Go. They define tests using the Go testing package, implement the ToCsvText function, and then refactor it using strings.Join for better performance. Multiple test cases ensure the correct handling of empty, single-element, and complex input arrays. Continue reading →

In this programming article, the author presents a challenge of converting an IPv4 address into a 32-bit integer. The process involves splitting the IP address, converting octets to integers, performing bitwise shifting, and using bitwise OR to combine the values. A C# function is provided for this purpose, along with tests and a refactored solution.... Continue reading →

This article discusses solving the “Top Words Challenge” in C# using regular expressions and LINQ. The author presents the challenge, assumptions, sample tests, and two solutions. The first solution uses regular expressions and LINQ, while the second solution refactors the code to be more concise using LINQ and regular expressions. The article concludes with a...
