Brush up your skills at solving problems using recursion.

Ace the C++ Coding Interview

Recursion is an important problem-solving approach. Every developer is expected to solve problems using recursion.
In this module, we'll start with the basics of what recursion is and why it’s important before diving into practicing solving actual questions. We’ll have access to detailed explanations and visualizations for each problem to help us along the way.
By the time we complete this module, we’ll be able to use recursion to solve complex real-world problems.

## Shuffle Integers

Suppose you have an array of $2^n$ integers arranged as:
