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!

Learn Ruby from Scratch

## Problem statement

Skim through the string documentation in the [Ruby documentation](https://ruby-doc.org/core-3.1.1/String.html), and look for a method that removes characters from a string. Using that method, try to delete the input characters from the input string in the exercise below.



### Example
```ruby
input_string = "Ruby is fun"
input_characters = "u"
result = "Rby is fn"
```
