Recursion
Recursion is a programming concept where a function calls itself to solve a problem. In the context of functional programming in C#, recursion is a powerful technique that’s used to solve complex problems by breaking them down into simpler subproblems that can be solved recursively.
In functional programming, the focus is on expressing computations as the evaluation of mathematical functions rather than changing state or modifying variables. Recursion aligns well with this paradigm because it allows you to define functions that operate on smaller pieces of data, gradually reducing the problem’s size until a base case is reached, at which point the solution can be computed and propagated back up the call stack.
Here’s a step-by-step explanation of how recursion works in functional C# programming:
- Base case: Every recursive function needs a base case. This is the simplest form of the problem that can be solved directly without further recursion...
