Hackerrank Ruby Control Structures - Unless Solution

# Hackerrank Ruby Control Structures - Unless Solution

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.

User has two public methods, is_admin? and update_score. Your task in this challenge is to use the control structure unless and update all elements of the array who are not admins.

Hint

unless user.is_admin?
user.update_score
end


or

user.update_score unless user.is_admin?


The above code is a Ruby one liner.

Explanation

unless is the logical equivalent of if not

### Solution in ruby

def scoring(array)
array.each do |user|
end
end
