TopCoder - BritishCoins· 6. December 2007, 22:02

Mi respuesta al problema BritishCoins (para que jale en la Arena de TopCoder solamente se pone la pura clase BritishCoins sin el namespace y obviamente sin la clase Tester.)

en C#

namespace TopCoder
{
    class BritishCoins
    {
        public int[] coins(int pence)
        {
            int pounds, shillings; //12 pennies in a shilling, 20 shillings in a pound
            pounds = pence / (20 * 12);
            pence %= (20*12);
            shillings = pence / 12;
            pence %= 12;
            int[] result = new int[3] { pounds, shillings, pence};
            return result;
        }
    }
    class Tester
    {
        static string ToS(int[] array)
        {
            string resultSt = "";
            foreach (int valor in array)
            {
                resultSt += valor + ",";
            }
            return resultSt;
        }
        static void Main(string[] args)
        {
            BritishCoins testCoins = new BritishCoins();
            System.Console.WriteLine("{0}", Tester.ToS(testCoins.coins(533))); // 2,4,5
            System.Console.WriteLine("{0}", Tester.ToS(testCoins.coins(0))); // 0,0,0
            System.Console.WriteLine("{0}", Tester.ToS(testCoins.coins(6))); // 0,0,6
            System.Console.WriteLine("{0}", Tester.ToS(testCoins.coins(4091))); // 17,0,11
            System.Console.WriteLine("{0}", Tester.ToS(testCoins.coins(10000))); // 41,13,4
        }
    }
}

en Ruby (igual, solamente seria la pura Clase BritishCoins (suponiendo que TopCoder tuviera como opcion Ruby) solo para documentar como queda el test con Test::Unit, en el futuro solo pondré las clases)

class BritishCoins
  def coins(pence)
    #~	int[] coins(int pence)
    shillings,pence=pence.divmod 12
    pounds,shillings=shillings.divmod 20
    [pounds,shillings,pence]
  end
end

if __FILE__ == $0
  require 'test/unit'
  class Test_BritishCoins < Test::Unit::TestCase
    def setup
      @a=BritishCoins.new
      @function='@a.coins(pence)'
    end
	  def test_0
      pence=533
      expected=2,4,5
      assert_equal(expected,eval("#{@function}"))
	  end
	  def test_1
      pence=0
      expected=0,0,0
      assert_equal(expected,eval("#{@function}"))
	  end
 	  def test_2
      pence=6
      expected=0,0,6
      assert_equal(expected,eval("#{@function}"))
	  end
 	  def test_3
      pence=4091
      expected=17,0,11
      assert_equal(expected,eval("#{@function}"))
	  end
 	  def test_4
      pence=10000
      expected=41,13,4
      assert_equal(expected,eval("#{@function}"))
	  end
  end
end
