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)
}

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 / 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._1*c; s + (t._2 * c) } }
}
