Black and White Thoughts

From time to time when i get bored i play a bit with Topcoder is a fun way to get better in solving problems. I decide to make approaches in different progarmming languages, above i post the problem statement and the solution i made in Ruby/Java, enjoy.

Problem Statement, SRM 355 div 2, 250 points:

In Russia, the Value Added Tax is 18% for almost all goods, with the exception of certain food items, which have a Value Added Tax of only 10%.

You are given a String product, the name of a product, and an int price, the price of the product before tax. You are also given a String[] food, each element of which is the name of a food product. If the given product is an element in food, it is a food item (and thus subject to 10% tax), and otherwise, it is a non-food item (and thus subject to 18% tax). Return the price of the product after tax has been added.

Java aprroach

public class ValueAddedTax {
    public double calculateFinalPrice(String product, int price, String[] food) {
        double res = 0.0;
        for ( int i = 0; i            if ( food[i].equals(product) ) {
                res = (double)(price*0.10)+price;
                break;
            }
            else
                res = (double)(price*0.18)+price;
        }                
        return res;
    }
}

Ruby approach 

class ValueAddedTax
    def calculateFinalPrice(product, price, food)
      food.each do |f|
        if f == product then
          res = (price*0.10)+price
          return res
       end
      end
      res = (price*0.18)+price
      return res
    end
end

I think is time for making a change for this tumblelog, in a deeper tech way. I just want to get better in whatever thing i do concerning my carrier. That’s why i will begin  with writting things about programming PHP/Java/Ruby are in my thoughts this days so i will begin with that. I was thinking in posting cool things about Tumblr too, when i find them of course.

 So stay tune :-)
