Hackerrank Ruby Control Structures - Each Solution

Hackerrank Ruby Control Structures - Each Solution

Beeze Aal

Ruby offers control structures that let you iterate through its collections. One such control structure is each.

As you already know, HackerRank conducts many contests, and for every user who participates in a contest we update their score once the contest ends. You will be given a method called scoring with an array passed as an argument. Elements of the array are of the class User.

User class has a method update_score.

Your task is to iterate through each of the elements in the array using each and call the method update_score on every element.

Hint

array.each do |user|
    # call update_score on `user` here
end

Solution in ruby

Approach 1.

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

Approach 2

def scoring(array)
    # iterate through each of the element in array using *each* and call update_score on it
    array.each do |user|
        user.update_score
    end
end
