Exercise Description

Build a method that replicates Ruby’s cycle method and iterates through an array a variable number of times, and have the method return an array that contains the full set of elements that were iterated through.

Example

cloned_cycle([1, 2, 3], 3)
# [1, 2, 3, 1, 2, 3, 1, 2, 3]

Real World Usage

Understanding how arrays work in Ruby is key to working with data collections, which is one of the most fundamental requirements of data-driven applications. This exercise will help you learn how to work with nested collections, add elements to an array, and override the basic looping functionality provided by collections.
