Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/likweitan/stutter

Write a method stutter that accepts a queue of integers as a parameter and replaces every element of the queue with two copies of that element for example [1, 2, 3] becomes [1, 1, 1, 2, 2, 2, 3, 3, 3].
