What is Recursion ?
Recursion in software engineering refers to a programming technique where a function calls itself in order to solve a problem. This concept is based on the idea of breaking down a complex problem into smaller, more manageable subproblems, solving each subproblem recursively, and then combining the solutions to get the final result.

Recursion is often used in situations where the problem can be divided into similar, smaller instances of the same problem. It is commonly employed to solve problems related to tree structures, searching and sorting algorithms, mathematical calculations (such as factorial and Fibonacci sequence), and more.

What are some of the key component cases?

1. Base Case: This is the termination condition that stops the recursion. Without a base case, the recursive function would continue calling itself indefinitely, leading to a stack overflow error.

2. Recursive Case: This is the part of the function where it calls itself with modified arguments to solve a smaller instance of the original problem.

Also, recursion can lead to concise and elegant solutions for certain types of problems, but it can also be less efficient in terms of memory usage and execution time compared to iterative solutions. Therefore, it's essential to use recursion judiciously, considering factors such as performance and readability of the code.
