Understanding Recursion Through Practical Examples

Recursion Recursion is the process of defining a problem in terms of itself For example, we can define

Two functions, functionA & functionB, are called indirectly by recursive calls in this example of indirect recursion in C Playground FunctionA

recursion 3 ) People use recursion only when it is very complex to write iterative code For example, tree traversal techniques like preorder, postorder

recursion The act of a function calling itself, recursion is used to solve problems that contain smaller sub-problems A recursive function can
