I was watching #numberphile and they presented a fun maths puzzle. I didn't see the solution. So I paused the video and decided to write a program and see if that helped to solve the question -- to me maths needs to be visualised for it help to understand it.
Whilst writing this #beginner #program , I realised that this a is a great program to test programming structure, algorithm deduction and efficient bitwise operation.

So today I will teach you (beginners) how to write this in #Python and I also show the C and Rust programs to show you Python beginners how easy these languages are.

Did my outcome help me solving this maths riddle? Not really, the video did though.
