recursion_examples VS khan-api

Here's an Python example recursive Ackermann and the iteractive Ackermann. They produce the same output.

Here's a bunch of Python recursion examples (I use these in the book): https://github.com/asweigart/recursion_examples/

Here is a recursive Ackermann function.

Here's the Ackermann function solved iteratively.

(I always get people saying, "some things do require recursion" and, no, they don't require it. Here's a non-recursive Python implementation of the famously recursive Ackermann function, and it has the same output as the normal recursive one.)

There is literally nothing that you can do with recursion that can't be done with a loop and a stack (because that's effectively what recursion is.) To prove it, here's an iterative version of the famously recursive Ackermann function. It's output is identical to this recursive implementation.

What I am looking for is a public API to create the UI tool I need. A public API exists on github: https://github.com/Khan/khan-api/tree/master

Khan Academy here.

I used this.

Education is a foundation of society. Yes, to this one! I love the story of the Khan Academy (https://www.khanacademy.org) and how it started as Sal Khan wanted to help his cousins

Really nice video tutorials www.khanacademy.org and their youtube channel

www.khanacademy.org

Khan Academy is free and fun, if you ever want to take another whack at learning math.
