randomNumbers.go code repetition

[rgerardi]

I like the example on randomNumbers.go but there's a lot of code repetition that makes the example not so clear. Perhaps there's a better way to process the arguments.

You are right that there is a lot of code repetition. However, proper argument processing with viper is explained at a different chapter. The main idea here is to understand the logic of the program.
