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.

Recursion

## Problem Statement

Given a sentence you will find that the letters can be divided into two segments; **Consonants** and **Vowels**. Vowels are the letters; *A, E, I, O, U* or *a, e, i, o, u*. In this challenge, you need to find the **total numbers of vowels** in a given string. 

The function where you must write your code is given to you and you **cannot** change the input parameters. 

Try the code out yourself before looking at the solution.

**Good luck**
