Gearing Up for More Problem Solving

Learn about similar methods for array and hash data types in Ruby.

Motivation

To become a better Ruby developer, we need more practice! In this chapter, we’ll solve different puzzles, and through them, we’ll explore the two new concepts of recursion and back-tracking. We also want to be more adept in our use of our data structures. Especially, when it comes to using built-in Ruby functions to quickly complete small tasks. Familiarity with methods defined for one data type might be helpful when we’re working with a different data type.
