Thank you for this course. I am slowly jamming all this information in my brain and it is slowly latching into empty pockets in my head. This is at least how I have felt in the last few weeks. The resources and videos on recursion are great. I feel like I understand the concept. And it seems "math" centric to use recursion to aid in a solution. Would you happen to have a real-world example of using recursion that would help someone like me who appreciates math when calculating a tip on a receipt but has not memorized the Fibonacci sequence by heart?
