In this post, we will solve Ruby – Enumerable – Introduction HackerRank Solution. This problem (Ruby – Enumerable – Introduction) is a part of HackerRank Ruby series.
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
