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.
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
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:
Hacker, output “It’s a Hacker!”
Submission, output “It’s a Submission!”
TestCase, output “It’s a TestCase!”
Contest, output “It’s a Contest!”
- for any other object, output “It’s an unknown model”
case(switch statement of Ruby)
- 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" end end
