Project Euler Problems

Implementations of Project Euler problems in Kotlin, Literate Coffeescript, Python, Rust, and Scala.

Kotlin

Requires a JVM and Kotlin installation on your system.

To run a problem use:

kotlinc -script 001.kts

Kotlin Installation (macOS)

Create a Kotlin development environment using SDKMAN.

$ curl -s "https://get.sdkman.io" | bash

Follow the caveats printed to enable SDKMAN in the current shell.

$ source "$HOME/.sdkman/bin/sdkman-init.sh"

Then install Java and Kotlin:

$ sdk install java
$ sdk install kotlin

Commands:

• sdk help to show commands.
• sdk current to show current SDK versions.
• sdk list to list available SDK.
• sdk install <sdk> to install a new SDK version.
• sdk use <sdk> to select a given SDK version for use.
• sdk uninstall <sdk> to uninstall a given SDK version.

Literate Coffeescript

Requires a NodeJS installation with Coffee on your system.

To run a problem use:

coffee 001.litcoffee

Python

Requires a Python installation on your system.

To run a problem use:

python 001.py

Python Installation (macOS)

Create a Python development environment using pyenv.

$ brew install pyenv

Follow the caveats printed and add the following to your .zprofile.

# Homebrew Pyenv initialisation.
if which pyenv > /dev/null; then eval "$(pyenv init -)"; fi

Commands:

• pyenv version to show current Python version.
• pyenv versions to list available local Python versions.
• pyenv install --list to show Python versions available to install.
• pyenv install <version> to install a new Python version.
• pyenv global <version> to select a given Python version for use.
• pyenv uninstall <version> to delete a given Python version.

Rust

Requires a Rust installation on your system.

To run a problem use:

rustc 001.rs
./001

Scala

Requires a Java installation on your system.

To run a problem use the bootstrap Ammonite script in the scala directory:

cd scala
./amm 001.scala

Java Installation (macOS)

Create a Java development environment using SDKMAN.

$ curl -s "https://get.sdkman.io" | bash

Follow the caveats printed to enable SDKMAN in the current shell.

$ source "$HOME/.sdkman/bin/sdkman-init.sh"

Then install Java:

$ sdk install java

Commands:

• sdk help to show commands.
• sdk current to show current SDK versions.
• sdk list to list available SDK.
• sdk install <sdk> to install a new SDK version.
• sdk use <sdk> to select a given SDK version for use.
• sdk uninstall <sdk> to uninstall a given SDK version.
