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

## Disadvantages of Recursion
Recursion, broadly speaking, has the following disadvantages:
* A recursive program has **greater space requirements** than an iterative program as each function call will remain in the stack until the base case is reached.
* It also has **greater time requirements** because each time the function is called, the stack grows and the final answer is returned when the stack is popped completely.
