Define recursion

Define recursion

Recursion is a programming technique where a function calls itself directly or indirectly to solve a problem. The idea is to break down a complex problem into simpler instances of the same problem, eventually reaching a base case that can be solved directly.

Advantages of Recursion

• Simplicity: Often simplifies code and makes it more readable, especially for problems that naturally fit a recursive pattern (e.g., tree traversals).
• 
  
• Reduction of Complexity: Breaks down problems into smaller, more manageable subproblems.
