First, I use a regex to strip the given sentence of any unwanted characters. My solution uses Perl-compatible regular expression matching, which is loaded from a separate module. There are a few other smaller rules that you will have to discover by reading and trying the included tests.
#RAINDROP PNG PORTABLE#
For example, Portable Network Graphics should be converted to PNG. Let's start working on those.įor this challenge, you must convert a phrase to its acronym. The 5 exercises that exemplify Analytical languages are Acronym, Isogram, Roman Numerals, Raindrops, and Space Age. While you can complete the monthly challenge by completing any 5 exercises, you will get an extra-special "year-long" #12in23 badge for completing the featured exercises. I'll be completed each of the 5 "featured exercises." These exercises are chosen by Exercism because they particularly highlight a scenario where this month's language theme is beneficial. With Hello, World! out of the way, let's get started solving 5 exercises so we can complete this month's challenge. I just had to make the program return "Hello, World!" instead of "Goodbye, Mars!" so I just had to change that one string. hello_world('Goodbye, Mars!').Īs usual, this one was incredibly simple. I want it to be as easy as possible to write code, debug it, run tests faster, and just get a better sense of the real-world experience developers might have with the language in general.Įxercism tracks always start with a required "Hello, World!" exercise just to make sure you can complete and submit everything okay. The main reason for doing this is so I can have access to more powerful developer tooling. This time again, I'll be installing and setting up a local development environment for this specific language. In Prolog, you use a strongly-defined set of rules to come to some conclusion that can be applied to huge datasets, making it a great match for integrating with databases. It's something I haven't seen anywhere else and sets Prolog in a class of its own in my mind. One thing that I found particularly interesting was that Prolog "backtracks" to find multiple solutions to a problem and select the best one. Indeed, it is used in some machine learning and language modeling applications. It makes heavy use of pattern matching to search through large databases for information. Prolog stands for "Programming in Logic." It works great for applications that can be expressed as a set of logical rules. The more I researched the languages, the more I became interested in logical reasoning. Ultimately, I figured the most important thing for me would be experiencing a language that makes me think about problems in ways I haven't before. I had to think about what I wanted to get out of this month. There are so many great options and they all excel at different things. I struggled to decide which language I wanted to use this Month. You can work toward the goal by completing exercises from Ballerina, Pharo, Prolog, Red, Tcl, and Unison. The focus is on languages that are quite different from mainstream languages. I'm documenting my experience with this challenge throughout the year.Įach month has a specific theme in mind. We'll provide resources and support to help you along the way, and you can track your progress and connect with other participants on our online community. The idea is simple: each month, you'll focus on learning a new programming language. If you're not familiar with the #12in23 Challenge, it's a programming-language learning challenge that tasks you with trying out 12 different languages in the year of 2023.
#RAINDROP PNG SOFTWARE#
This month I'm focusing on Prolog to hopefully "shift" my mind into thinking about different ways I can tackle the challenges that come with software development. That's why, even in the fifth month, the #12in23 Challenge is still such an exciting endeavor for me. It helps you expand your knowledge, learn new techniques, and approach problems in unique ways. Learning new programming languages is an important aspect of a software developer's journey.
