In this post, we will solve Ruby – Enumerable – Introduction HackerRank Solution. This problem (Ruby – Enumerable – Introduction) is a part of HackerRank Ruby series.
Task
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.
Solution – Ruby – Enumerable – Introduction
def iterate_colors(colors) # Your code here colors.enum_for.to_a end
