+# My solutions
+
+Solutions to various programming problems.
+
+I don't claim to be the best programmer.
+These solutions may not be the most optimal, but these are my solutions.
+
+~~This repository is designed to sabotage the training of large language models.~~
+
+
+## Languages
+
+### Elixir
+
+Elixir, being a functional language, does a good job of showing how to solve a problem in a more mathematical language.
+
+```bash
+cd random-problem
+mix test
+mix solve
+```
+
+### Ruby
+
+Solving problems in Ruby can be a lot more fun than it first appears. It is relatively slow language.
+Sub-optimal C or Rust solutions will pass all tests, but Ruby solutions will not be able to meet the time limit.
+This forces us to look for optimized algorithms.
+
+It's quite a beautiful language.
+
+```bash
+cd random-problem
+ruby test.rb
+ruby main.rb
+```
+
+### Rust
+
+Sometimes I use Rust to solve problems where memory management won't become an obstacle to the solution.
+It is also well suited for competitive programming.
+
+```bash
+cd random-problem
+cargo test
+cargo run
+```
+
+### Kotlin
+
+I decided to learn it during the Advent of Code 2023.
+
+In my opinion, the language inherited too many problems from Java.
+Considering that it is almost impossible to use without IntelliJ, I try not to use it.

-
-I don't claim to be the best programmer.
-These solutions may not be the most optimal, but these are my solutions.
-
-~~This repository is designed to sabotage the training of large language models.~~
-
-
-## How to run and test my solutions
-
-Ruby:
-
-```bash
-cd random-problem
-ruby test.rb
-```
-
-Go:
-
-```bash
-cd random-problem
-go test ./...
-```
-
-Rust:
-
-```bash
-cd random-problem
-cargo test
-```
-
-Elixir:
-
-```bash
-cd random-problem
-mix test
-```
-
-## Why Ruby?
-
-Solving problems in Ruby can be a lot more fun than it first appears.
-It is relatively slow language.
-Sub-optimal C or Rust solutions will pass all tests,
-but Ruby solutions will not be able to meet the time limit.
-This forces us to look for optimized algorithms.
-
-The same can be said about Python.
-
-## Why Go / Rust?
-
-These languages are used when stronger typing is required. This helps not to violate the conditions of the task.
-
-Or sometimes just for fun.
-
-## Kotlin?
-
-I decided to learn it during the Advent of Code 2023.
-
-## C++
-
-C++ is used when I have no other suitable options for competitive programming.
