Hello coders, In this post, you will learn how to solve HackerRank Ruby Enumerable Introduction Solution. This problem is a part of the Ruby Tutorial series. One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions.
HackerRank Ruby Enumerable Introduction
Let’s get started with HackerRank Ruby Enumerable Introduction Solution
Problem Statement
In control structures tutorial, we learned about various methods to iterate over a collection like unless, loop and the most commonly used each method.
Ruby, however, provides an Enumerable module which packages a bunch of methods which can be used with any other class by including it (referred to as mixing in). That means that programmers don’t have to write all those methods many different times for different objects. As long as the custom object defines an each method and includes Enumerable module, it can get access to all of its magic.
In this challenge, you have been provided with a custom object called colors that defines its own each method. You need to iterate over the items and return an Array containing the values.
HackerRank Ruby Enumerable Introduction Solution
def iterate_colors(colors) # Your code here colors.enum_for.to_a end
Note: This problem (Ruby Enumerable Introduction) is generated by HackerRank but the solution is provided by Chase2Learn. This tutorial is only for Educational and Learning purpose.
