Ruby Control Structures – Case (Bonus Question) Solution

In this post, we will solve Ruby Control Structures – Case (Bonus Question) HackerRank Solution. This problem (Ruby Control Structures – Case (Bonus Question)) is a part of HackerRank Ruby series.

Task

This is a bonus question. Feel free to skip to the next challenge.

HackerRank is written in RoR and we have various classes defined in it. Some of them are

  1. Hacker
  2. Submission
  3. TestCase
  4. Contest

etc.

You have been given a function where an object which may or may not be of the above mentioned type is sent as an argument. You have to use the case control structure in Ruby to identify the class to which the object belongs and print the following output:

  • if Hacker, output “It’s a Hacker!”
  • if Submission, output “It’s a Submission!”
  • if TestCase, output “It’s a TestCase!”
  • if Contest, output “It’s a Contest!”
  • for any other object, output “It’s an unknown model”

Note

  • use case (switch statement of Ruby)
  • use puts for printing
  • Ruby Docs on case

Solution – Ruby Control Structures – Case (Bonus Question)

def identify_class(obj)
    # write your case control structure here
    case obj
        when Hacker
            puts "It's a Hacker!"
        when Submission
            puts "It's a Submission!"
        when TestCase
            puts "It's a TestCase!"
        when Contest
            puts "It's a Contest!"
        else
            puts "It's an unknown model"
