! Warning !

Creating a repository or website like this is discouraged by Codewars.
You should not look at any solutions to Kata until you have completed it yourself or at least took the time to think about your own approach.

Codewarriors should not submit my solutions as their own.

This website is a collection of my own solutions to challenges from Codewars.
The purpose of this website is to show my coding and problem solving skills to the potential employer.
The programming languages presented here are those that I have had contact with, not only those I can code freely with.

Codewars vocabulary

Kata - problem to solve
Kyu - proficiency of users and the difficulty of Kata
Dan - proficiency of users higher than Kuy
Codewarriors - users of Codewars

What is Codewars?

Codewars is an online platform that offers sets of programming challenges to solve in various programming languages. Users can choose from different levels of difficulty, starting from basic topics to more advanced algorithms and programming techniques

On Codewars, the challenges are organized in the form of "kata" - which are sets of problems to solve. After solving a challenge, users can submit their solutions, which are then reviewed by other members. For each correct solution, users earn points and move up to higher levels of mastery.

The Codewars platform is not only an excellent place to learn and practice programming, but also allows interaction with other programmers through discussions about solutions and techniques

Ranks

There are two classes of ranks, Kyu and Dan.
They are borrowed from a system in Japanese martial arts, which is in turn borrowed from the game of Go.

Kyu

Used to indicate the proficiency of users and the difficulty of Kata.
Counted downward (8 Kyu to 1 Kyu) because it indicates the number of degrees away from master level (Dan).

Dan

Used to indicate the proficiency of users once they reach master level.
Counted upward (1 Dan to 8 Dan). Black belts in martial arts are Dan level.

White (Beginner)

8 kyu represent a beginner level. At this level, the kata are only challenging for users new to programming. This includes programming tasks such as:

Defining a simple function (i.e. hello world)
Basic variable assignments
Fixing basic syntax issues
Trivial algorithms such as basic if/else statements

7 kyu represent a beginner programming level. At this level, the kata will generally challenge users on their core language and API reference knowledge. Tasks such as:

Iterating arrays and returning a subset of values
Basic data type manipulations
Basic functional or object-oriented concepts
Basic Regular Expressions

Yellow (Novice)

6 kyu represent a novice programming level. At this level, the kata will start to include more advanced algorithmic challenges and more complex language features. It includes:

Complex language features (closures, scopes, monads, etc)
Complex OOP/Functional concepts
Basic Design Patterns
Complex Regular Expressions

5 kyu represent a novice programming level. At this level, the kata are similar to 6 kyu but more challenging. It includes:

Complex language features that require mature OOP/Functional concepts
Advanced OOP/Functional concepts
Complex Design Patterns
Advanced regular expression usage

Blue (Competent)

4 kyu represent a competent programming level. At this level, the kata begin to take some serious thought to complete. They include tasks that may handle:

Computer science concepts utilizing complex algorithms
Advanced design patterns
Understanding intricate business requirements
Advanced concepts such as concurrency, parallelism, meta programming and cryptography

3 kyu represent a competent programming level. At this level, the kata are similar to 4 kyu but are more challenging. They include tasks that may handle:

Computer science concepts utilizing advanced algorithms
Ability to implement advanced requirements in a scalable fashion
Basic AI/machine learning algorithms
Detailed usage of advanced concepts such as concurrency, parallelism and cryptography

Purple (Proficient)

2 kyu represent a proficient programming level. At this level, kata require a mature understanding of complex programming concepts - concepts such as:

Complex AI/machine learning algorithms
Reverse engineering techniques
Basic interpreters and compilers
Basic mini-programs with multiple feature requirements (such as a basic Markdown parser)

1 kyu represent a proficient programming level. At this level, kata are similar to 2 kyu but more challenging. They may include concepts such as:

Advanced AI/machine learning algorithms
Complex interpreters and compilers
Complex Mini-programs with multiple feature requirements (such as a complete Markdown parser)
