In this post, we will solve Ruby Control Structures – Unless HackerRank Solution. This problem (Ruby Control Structures – Unless) is a part of HackerRank Ruby series.
You’ve updated the score of every HackerRank user who participated in a contest. Sometimes, HackerRank admins also participate in a given contest but care is taken to ensure that their submissions do not get any score and their score is not updated.
Like the previous challenge, you are given a method
scoring with an array passed as an argument. Each element of the array is of class
User has two public methods,
update_score. Your task in this challenge is to use the control structure
unless and update all elements of the array who are not
unless user.is_admin? user.update_score end
user.update_score unless user.is_admin?
The above code is a Ruby one liner.
unless is the logical equivalent of
Solution – Ruby Control Structures – Unless
def scoring(array) # update_score of every user in the array unless the user is admin array.each do |user| user.update_score unless user.is_admin? end end
