MergeSort Algorithm in Ruby

When learning about sorting algorithms, I wanted to implement them to help me understand them better. This algorithm was originally invented by John von Neumann in 1948.

The Ruby script attached explains in real code what is going on. Play about with it.

How does the algorithm work?

Step by step:

• Pass through an array of unsorted numbers (i.e. [4, 3, 2, 10])

bih

class Fixnum
	def is_palindromic?
		self.to_s == self.to_s.reverse
	end
end

100.is_palindromic? # => false
2002.is_palindromic? # => true

Parse yo' Gemfile

Want to parse a Gemfile? This finely does it. How you may ask? This file replicates the entire Gemfile functions (aka source, gem and group) and then executes the Gemfile in Ruby.

Security

As it executes the Gemfile, it can potentially contain malicious Ruby code. This could import your project and perform commands and I would recommend executing it in a safe/sandbox environment. An example would be through an external server and use an API. This way it is very easy to replicate your software and it is totally harmless.

<3 Have fun.

Example

Example Gemfile:

bih

# Need a way to kill the addictiveness of the 2048 game? Paste this into yo' console.
# http://gabrielecirulli.github.io/2048/

var t;(t=new GameManager(4,KeyboardInputManager,HTMLActuator,LocalStorageManager));t.startTiles=0;t.setup();while(t.grid.cellsAvailable()){t.grid.insertTile(new Tile(t.grid.randomAvailableCell(), 1024));};t.actuate();
