In this HackerRank Ruby Control Structures - Unless problem 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.
