Today I try to explain to simple principal of factorial to my daughter, but it took some time. She did not see the use of it yet. Maybe the concept of factorial and recursion was still a bit too complicated. She is just 9 so I don’t blame her.
When I was around her age (actually 10) , I was excited because my dad bought a Commodore 64, it opened up a new world for me. I started fiddling with it and after a while I start programming on it. When I learned about recursion a complete new world opened for me. It finally got me a passion and I am making a living with it.
