What are some common recursive algorithms?

What are some common recursive algorithms?

Common recursive algorithms include factorial calculation, Fibonacci sequence, and tree traversals.

Can you explain how the Fibonacci sequence works recursively?

Sure! The Fibonacci sequence is defined as F(n) = F(n-1) + F(n-2) with base cases F(0) = 0 and F(1) = 1.

What are the advantages and disadvantages of using recursion?

Advantages include simplicity and clarity, while disadvantages can be higher memory usage and risk of stack overflow.

Are there any iterative alternatives to these recursive algorithms?

Yes, many recursive algorithms can be implemented iteratively, such as using loops for Fibonacci or stack for tree traversals.
