title: Converting snake case to normal sentence in Ruby
body: <p>I'm trying to convert a string in snake case to normal case(Eg: "hello_world" to "Hello world")</p>
  
  <p>I'm pretty new to ruby, and I'm using it with Rails. I found this question <a href="https://stackoverflow.com/questions/9524457/converting-string-from-snake-case-to-camelcase-in-ruby/39716710">Converting string from snake_case to CamelCase in Ruby</a>, and it seems like there is a function for that usecase (<code>.camelize</code>). Is there anything that I can use inbuilt like that? If not, how can I achieve this?</p>
