sebnozzi / toRoman-terse.scala

Created September 10, 2013 10:53

In the spirit of this article ( http://java.dzone.com/articles/merits-verbosity-and-flaws ) I wanted to re-write the implementation in a more verbose and readable fashion. Even if the result is not a cool one-liner ;-)

	def toRoman( v:Int ) : String = {
	val romanNumerals = List(1000->"M",900->"CM",500->"D",400->"CD",100->"C",90->"XC",
	50->"L",40->"XL",10->"X",9->"IX",5->"V",4->"IV",1->"I")

	var n = v
	romanNumerals.foldLeft(""){(s,t) => {val c = n/t._1; n = n-t._1c; s + (t._2 c) } }
	}

sebnozzi / 0-calendar.rb

Last active December 22, 2015 16:29

Exploring code transformation from Ruby to Scala. Taken from http://rosettacode.org/wiki/Calendar#Ruby . Taking Ruby as the original version, I want to show that it's possible to write more or less the same code in Scala. Except for the fact that Ruby comes with more "batteries included" than the JDK/Scala.

	require 'date'

	# Creates a calendar of _year_. Returns this calendar as a multi-line
	# string fit to _columns_.
	def cal(year, columns)

	# Start at January 1.
	#
	# Date::ENGLAND marks the switch from Julian calendar to Gregorian
	# calendar at 1752 September 14. This removes September 3 to 13 from

sebnozzi / FizzBuzz.scala

Last active December 12, 2015 00:18

This is my "boring", "conservative", verbose, "my momma should grasp it" version of FizzBuzz...

	object FizzBuzz extends App {

	implicit class MyInt(thisNumber: Int) {
	def isDivisibleByOrHasDigit(other: Int) = { isDivisibleBy(other) \|\| hasDigit(other) }
	def isDivisibleBy(other: Int) = (thisNumber % other == 0)
	def hasDigit(c: Char): Boolean = thisNumber.toString.contains(c)
	def hasDigit(x: Int): Boolean = {
	assert(x >= 0 && x < 10, s"Number should be 1 digit long (found: $x)")
	hasDigit(x.toString.head)
	}
