If you’ve ever struggled with solving coding problems using recursion, or if you’ve just got an interview coming up and want to brush up on your knowledge, you’ll definitely find this course helpful.
 
You’ll start with the basics of what recursion is and why it’s important before diving into what it looks like in practice. You’ll see how recursion can help you solve a variety of different math, string, and data structure problems, using interactive code playgrounds you can execute directly in your browser. You’ll have access to detailed explanations and visualizations for each problem to help you along the way.  
 
By the time you’re done, you’ll be able to use what you’ve learned to solve complex real-world problems, and even advance more easily through your interviews at top tech companies.

Recursion for Coding Interviews in C++

## 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**
