Learn the basics of Ruby with hands-on practice.

Become a Ruby Professional

Do you want to be an interpreted language geek? Are you tired of getting entangled in the dense syntaxes? Does it irritate you to compile your code to machine language first? Are you looking for an easy-to-use scripting language? Well, Ruby is the best pick for you then!
This introductory module will be providing you with hands-on practice with the support of a bunch of interactive illustrations, exercises, and the integral topics of variables, built-in classes, objects, conditionals, blocks, and much more!

## Problem statement

Now, change the `greet` method so that instead of always using `"Hello "`, it picks a random string from the array `["Hello", "Hi", "Ohai", "ZOMG"]`.


### Example
If the name `“Ada”` is passed as an argument, then it should print out either `"Hello Ada!"`, `"Hi Ada!"`, `"Ohai Ada!"`, or `"ZOMG Ada!"` every time you run the program.



> **Note:** You just need to provide the definition of the method, and it will be automatically evaluated on the given input value.

### Try it yourself
To complete this task, you’re expected to either consult the documentation or look at the hint below.
