can you explain how to do this program and what is required? i didn't understand it when i read it: https://exercism.org/tracks/ruby/exercises/resistor-color-duo in ruby

To understand and complete the exercise from the given link, "Resistor Color Duo" on Exercism, you will need a basic understanding of Ruby programming language and the concept of a resistor color code.

The exercise requires you to create a Ruby program that will take in two resistor color bands as input and output the corresponding numerical value of the resistor. Resistor color codes are used to represent different values of resistors in electrical circuits. Each color corresponds to a digit or multiplier, and the combination of colors represents a specific value.

To complete the exercise, you need to follow these steps:

1. Read and understand the exercise description on the Exercism website. It explains the problem statement and the expected input and output.

2. Set up a Ruby development environment on your computer if you haven't already. You can use an IDE like Visual Studio Code or any text editor to write your code.

3. Create a new Ruby file and open it in your chosen editor.

4. Define a method, let's say ResistorColorDuo.duo, that takes two resistor color bands as input.

5. Implement the duo method to look up the corresponding numerical value of the resistor, based on the given color bands. You can use a lookup table or case statements to map the colors to numerical values.

6. The output of the duo method should be the combined numerical value of the two resistor color bands.

7. Save the file with a suitable name and a .rb extension.

8. Open a terminal or command prompt and navigate to the directory where you saved the Ruby file.

9. Run the Ruby program by typing ruby filename.rb in the terminal. Make sure you have Ruby installed on your computer.

10. Test your program with different inputs to verify that it is working correctly. You can use the examples and test cases provided in the exercise description.

Once you have completed these steps, you can submit your solution to Exercism for feedback and review. Remember to follow the Exercism guidelines for submitting your solution.

I hope this explanation helps you understand how to approach the "Resistor Color Duo" exercise in Ruby. Happy coding!

Note: The exact implementation details may vary based on your programming style and choice of helper libraries.
