Ruby. The Best of All EVER.

Simple. Beauty. Force.

Just Works.

require 'sinatra'
get '/' do
"Hello World!"
end

Web-server with hello-world-main-page. 4 lines. :)

p Array.new(gets.to_i){gets.to_i}.sort

Input (any size), sorting and output array. 38 symbols.

Functional programming in the box with OO together.

Sorry for bad English. :) I'm from Russia, and I speak in Ruby.
